Quick Question about the D&D 5E By Roll 20 Character Sheet

I've been using this for a while now for NPCs and Monsters that aren't in the SRD.  Tonight I just discovered the NPC check box.  I noticed however that when I check it, everything except the stats and HP go away.  No name.  No Armor Class.  No attacks despite being in the attacks box under the character sheet.  Is this the way it's supposed to work or am I using the sheet poorly?

That's how the sheet functions, NPCs don't share many stats with the PC version of the sheet, unfortunately. It's due to how the sheet was designed originally, and not really ideal. Newer sheet's like Pathfinder 2E have been designed better from the ground up to have more overlap between the two. Remember to check the Help Center and the Community Wiki for info on Roll20 features so you're not missing out on more things-

The D&D 5th Edition by Roll20 Sheet suffers from being the prototype. It has a lot of things on it that would be better were they done with the experience gained from its pain points. Many (certainly not all) attributes found on the PC list can be found by appending "npc_" to the beginning: "ac" becomes "npc_ac", etc.

I was afraid of that, ah well.  Thank you for the replies!
