We have a content type, "Tasks", that have a number of fields, one of which was mandatory when it was created. We have a list that makes use of this content type, and now we want the field to be non-mandatory.
We have tried changing the field to be non-mandatory on the list itself, and it works for a limited time, until someone else changes another field, adds a field or in some similar way changes the list. NOTE: The list changes a lot, so correcting it every time becomes a major hassle.
We have tried making it non-mandatory in the content type (from the web), but the same effect occurs once someone alters the list - the field is reverted back to mandatory, both on the list and the content type.
Am I changing the field in the wrong place? Any way to prevent it from turning back to mandatory for good?
