I have a acct customization project that i am trying to deploy into a client sandbox. im running into issues because of this:

Feature - WMSSYSTEM:required

. After doing some digging, it seems that certain properties of custform require the WMSSYSTEM to be enabled. Any one know why this is the case and what a possible solution would be?

This is a known bug, where its added to manifest when it's not needed. Have you tried removing it from the manifest manually?
