D&D 5E by Roll20 NPC sheet

Hi, I am a new users in roll20 (and also French so sorry for my English). I try some rules system on roll20 and come back on D&D5 with my players. I am using Roll20+ account. My issue: I try to set token bar 3 to follow NPC hit point as for Players. I am using D&D 5E sheet by Roll20, 1) I create a NPC sheet for a monster (or a common NPC) 2) I initialize the monster NPC sheet with drag & drop from Compendium (the game is configure to use D&D5) 3) I put a new token on a map (and set some properties, I try also without modify anything) 4) I bind the token to NPC sheet via the token combo box (to pick up the right NPC sheet) 5) I bind the bar 3 with hp ==> Issue it doesn't work, the bar 3 bubble keep empty     And when I set a value, he bar associated to bar 3 appear as for Players (to follow the health status) I don't understand why the bubble isn't bind with the current hp value (or at least its initialize with the max HP value) event if all monsters based on this NPC sheet have the same HP health. Would you confirm please or If I am missing something I understand than, I have to take an account Roll20 Pro, just to to have a way to manage HP (with "token-mod" macro set). And to be able to generate for each NPC a specific hp value

I'm not familiar with that sheet, but you dont need to be a Pro user to get this behaviour. So there's a problem with the sheet, or the steps you are taking. There's a number of things that could cause this problem. I'd double check the attribute names, and look to see if there's another attribute you should be using. Some sheets have different stats for npcs and pcs. Some attributes are autocalc fields (a special kind of attribute) which dont currently work with Token bars. 

Thanks for your help

If you alt+double-click on the token, does it open the correct NPC sheet? If you then click on the cog icon in the top right of the NPC sheet, does it display the correct HP in its stats? Are the sheets in French or English? Maybe someone has mistyped the Attribute name if it's a translated sheet. It should just be hp for a 5e sheet. Do the other NPC stats, like AC, function properly in the token bars? Also keep in mind, you generally don't want to link NPC HP to the sheet for common enemies. If you have 6 Goblin tokens all linked to the same sheet and one takes damage, the HP of all 6 Goblins tokens will be changed at once, because they are all linked. Individual enemies & bosses are fine to link if you wish though.

Thanks for your answer Initially, I set my account in FR, I switch to UK this morning to see if any changes : no changes. So D&D Roll20 sheet came in UK now and when I open the sheet from the token I open the correct sheet (in FR and in UK) AC work well with token bars (in French and in UK). I used " npc_ac " attribute for NPC. Unfortunately I didn't see " npc_hp " so I used " hp ". I just use these 2 attributes on the token bars. The curious is if I initialize the token bar bubble with a value, I come back to the Players character behavior for HP (even if is the same for all instance of NPC). But without visibility to value generated by the compendium (I have to bind the token to the sheet and open the sheet just to pick the HP value). My purpose is to gain time when I use compendium and drag & drop. I already know the behavior and the issue for multiple instances of a same NPC sheet (as goblin). I regret to be oblige to change to Pro account to have a way to walk around. So with a Roll+ account, I manage several sheet (one for each NPC sheet on the field).
