Bug? Error message when opening encounters in Raging Swan Shadowed Keep module

[Geometer]

I've just bought the new Raging Swan Press module Shadowed Keep on the Borderlands. Reading through it, whenever I open an Encounter or an NPC stat block I get an error message (see attached screenshot). It doesn't seem to affect performance, as far as I can tell, but it's a constant annoyance

Does it register that error with no extensions? That looks like the one that pops up with the Kit-N-Kaboodle extension in 5E. You can keep the console from popping up if you type in the command /console skip in the chat and press enter. Not a permanent fix but a band-aide.

Salutations Bonkon. You're correct, it's a clash with extensions - not the one you mentioned, just some that need updating. I really should have figured that out for myself . Obliged
