This is an issue that happens often but not always, everytime some parameters are entered in the ItemRevision Master disappear after revising.
Did it ever happen to you? Do you know how it can be resolved?
Anyway its TC10.
Thx in advance!
I am yet to come across this issue in TC11.x.
Yes I did observe that odd behavior upto TC10.x.
If you can share/message me few more details, I can try it out in my local TC11.x environment.
