Save Pdf to DT3: folder names missing

When using the Save PDF to DT3 option from the print menu in Safari the list of folders to select has lost the folder names - the folder icons are displayed but not the names. This has only recently started happening. I have tried restarting DT and also rebuilt the database without any impact. Any ideas?
Thanks

This is a known issue (especially on Big Sur), the next maintenance release will fix this.
