How to clear format strings suggested in "convert>tag - filename" dropdown?

Mp3tag remembers different format strings we used in past conversions, which is great, but my drop down list of suggestions became overpopulated, including some past typing errors.
I would like to cleanup these entries, is it possible?
Thanks a lot!

Click the arrow to the right and you see these options.

When you highlight the one you want to delete you can also SHIFT+DELETE to remove them one by one.

Thank you, I totally missed it!
