When opening a backlog item the first field is active and after closing the item it shows "....saved".
This will not be logged in its history, but shows up in "last changed". Why and what could we do to stop this?
What is the type of the first field? Is it a memo (description field)?
Does it happen with all the backlog item types (epics, features, defects, user stories, quality stories)?
Does it happen with tests?
Thanks for the questions! They led me to trying different things and it happened that switching fields - the first one was a numbers field and is now a list field - stopped the action.
What release are you using?
I tried to reproduce the issue on 15.0.20 by moving the story points field of a defect to be the first field in the form (because you said that it happened with a numeric field) but it worked fine for me.
Is the numeric field you were referring a UDF?
