Changes for Metadata in Thumbnail grid does not work

Hi all,
I tried to change the displayed metadata for a specific thumbnail grid for an album template . Unfortunately it was only possible to turn the display of the metadata on and off but the displayed metadata was always the {Title}. Even when other metadata tokens e.g. {Filename} were put into the field. I tried the change with firefox and Edge. Always the same. May this be a bug or do I have to change it anywhere else instead of the thumbnail grid settings?

If using Lightroom, after making changes to the template you need to republish

Hi, I had published the gallery before but without marking the gallery for republishing. Now I have published it again and it worked. Thank you very much
