MacSparky's shortcut SMFG 4.5 - Add Date to Name

A question for anyone who bought MacSparky’s wonderful shortcuts for mac fieldguide.

Shortcut SMFG 4.5 - Add Date to Name only adds the dash and old filename for me, no date. I’ve tried changing format of date, using a specific date, and checking all the variables, though this is really about the first shortcut that I’ve attempted to use, so I’ve stumbled on the first hurdle.

Could this be a result of a shortcuts update perhaps, and would someone else who bought the guide try it out for me? It’s very possible I’m doing something done, I’m new to using shortcuts, but have been using KM for sometime, so I’m not completely clueless!
