Thank you for reporting this bug. We will make it our priority to review this report.
Duplicate of 42 and 74.
We'll resolve this issue. Do you have a project file that you can attach so we can test?
If you open up the .xds file is it correct in the project file after saving and only broken when opening?
Could you please do me a favor and create a brand new project, then type the characters within the grid columns save only one time and then post the project file here?
This file appears like you opened it and then saved it again (which is where the bug was).
I want to verify that is the case and this issue has indeed been fixed. If you check the other two threads that this bug was a duplicate of, you'll see they've been resolved.
