Probably needs to be reported to their devs

Thank you so much for letting me know, I really appreciate the help you have done so far.
I would fill out request a bug report to them and if you don't mind, may I send this thread to them as well so they would be able to know the current situation?

In the meanwhile, I would take a look around the conflicted mod so that I could get an idea of the said mod.
Thank you again!!

Sure, go ahead, I think there's problem if said Pavise item is placed in Traveler's Backpack crafting grid - it might be reproduced but needs tests.
