So in the gas gauge C172 default deluxe edition aircraft for FS2020, the Garmin 530 does not show the VOR data. The CDI has the signal, but the text for ID, TRK and DIST is not shown on the screen. I love this plane but without DME I cannot work on the P2 in this aircraft. (DME ARC). Am I crazy and missing a setting? Or is this feature INOP?

I would say that it is INOP, as with pretty much everything in FS2020. I don't have it myself, so I wouldn't know.
