But I am not really proficient with that, maybe the modules still need to be updated after the code is changed. Although: When you made sure you updated everything, then go into the library of this campaign, to the modules, then right-click on that module and revert changes :) That may do the trick (but it will revert all changes, alternatively you can right-click on NPCs to revert just them (you may need to open the sheet first to make that possible, until you see a quill on the book next to its group name), but that you'd need to do for every single NPC)
I hope this helps :)
(in general, module updates to things you also already have "edited" are not automatically carried over, you need to click "revert changes" then)
