pathfinder 1e (natha sheet) NPC "NPC Building" message the last two days

I manually build an NPC babau demon a couple weeks ago and have been able to access the sheet multiple times since I made it with no issue. starting about 2 days ago, it now has the "building NPC" message on top and cannot access any of the stats or anything for it. I have disabled Adblocker, I have cleared cache and cookies. I've tried to open in a different browser (I use Chrome normally but tried Edge and also incognito) no change. Because of how often this one shows up in the game, I really do not want to have to remake it and repopulate it. Is there any way to check the back end to see what might be causing an issue.  I do not have any scripts, macros, or APIs loaded in this base game to try to avoid any potential issues. 

Usually this means the "NPC Build Flag" attribute has become stuck. It happens occasionally.  To fix: Switch to the "Attributes tab and look for the NPC Build Flag. Change it from 1 to 0, and that should stop the building message being stuck.  Note: Unless I am mistaken, the "natha sheet" is better known as the "Pathfinder by Roll20" sheet (the "official" one).
