ISSUE: Filenaming scheme - removing a section does not show

In the export window the file naming scheme works ok, but when I want to change the scheme: For example remove a section of the scheme like ‘TrackName’ than it does not immediately show this removal. And I cannot add new sections to the scheme.
I have to close the window and open it to make sure it is ok.
Yes it will also reflect in the filename preview but that is very small and I have longer than filenames sometimes.
