"Why cant deprovisioning def base def be found?" error

When we try assigning values to new PSPNG provisioning attributes [1] on folders, we are getting a "Why cant deprovisioning def base def be found?" error. See below.

It's our belief that this was working properly before applying API patch 107.

Do you know of any workaround? As this is a major blocker for us for some critical development work ...
