Pathfinder by Roll20 NPC sheet doesn't auto-update?

This may be a known issue, but whenever a change is made to the NPC sheet, it does not update any other part of the sheet. Is there a way to fix this or do we have to manually redo a sheet any time we want to change an attribute? The PC sheet works just fine.  We are using the Rise of the Runelords Anniversary Edition module, if that makes a difference.

This is normal behavior.  Part of the reason for the npc sheet is to use different attributes that are divorced from the javascript sheetworkers of a normal PC sheet.  This is to cut down on the sheetworker/data load as you build the amount of active sheets in the game.  NPC sheets are manual adjustment only. I generally put any buffs available to an npc in the attack, save, or skill notes to remind me to add +X if Y bonus is active.  If you are running a really complex enemy, then you might want to build them on a PC sheet.  Just don't go overboard with pc sheets or you have the chance of experiencing game lag just from the sheet load on top of a relatively large adventure path.
