Yes, I also experienced (for years and years) this annoying issue on my rigs, and it even goes further:
I’ve got a lot of ruler tracks in my templates which don’t show the time-format they were saved in.
I noticed though, that when I set all my Ruler Tracks and the Main Ruler to the same format, and I change the Main Ruler to another format (e.g. when I work all the time in “TIMECODE” and I switch it into “BARS & BEATS”) then; the next time I open Nuendo all of my Ruler Tracks have changed to this new format.
