Missing and inconsistent metadata between workspaces in Premiere
I am getting different results in metadata depending on which workspace I am in.
In the Assembly workspace I import video files from the Media Browser tab. I have created a new metadata text field called "Tags". Entered some info in Comment and Tags fields. When I switch to Metadata tab in the Assembly workspace the data in comments is there but the Tags field is blank. If I now put data in Comment and Tags and then switch to the Project tab the Comment data shows but not the Tags. (blank or different data in each).
Now I switch to the Editing Workspace, Project tab. Now the project tab Tags field shows what the Assembly, Metadata tab does.
But now the Creation Date info is blank. Same thing with the Metalogging workspace, no creation date and different Tags info from the Assembly workspace. Assembly workspace does have info for Creation Date.
If I make a subclip in the Assembly workspace, the Tags info copies to the subclip but not the comments. If I make a subclip in the Editing workspace, neither Tags nor Comments carry forward. Same thing for Metalogging workspace.
Why is the custom text field "Tags" inconsistent?
Why does the Tags field transfer in some cases to the subclip but not others?
Why is creation date a blank field in everything but the Assembly workspace?
