Saving workspace not working

Saving workspace is too buggy. Here are the cases which happended;
1. When I save a workspace and assign it a keyboard shortcut. And after that I save another workspace. Then the new workspace doesnt show in prefrences to assign shortcut too. This happend earlier too.

2. Once davinci been restarted the shorcut stops working. I checked my shortcut profile is not present.

3. After that the workspace start been showing up but without options of loading the workspace.
