The team was aware of this issue, and it has been fixed in Premiere Pro beta version 25.6.0 build 89 and later. The fix will be included in the next stable release, 25.6.0.
Have you tried what jamieclarke said? On my end, it doesn't help. Saving things like settings and preferences in Premiere rarely works great. Even the Preview Area, which I like to switch off on some Workspaces, enables itself back on when switching Workspaces in the Project Panel.
Hi @alireza_0216 - Have you tried saving the metadata layout?
Once you have the columns arranged the way you want, right-click on any column header and choose Metadata Display. Then, click the Save Settings button and give your layout a name.
After that, be sure to go to Window > Workspaces > Save Changes to this Workspace to preserve the layout with your current workspace.
Give that a try and let us know if it resolves the issue.
