Changed project sample rate with some tracks frozen...UGH??!

Converted an older project from 44hz to 48hz, and didnt notice that some tracks were frozen.

It seems that they didnt convert or something, even though all of the audio parts in the Pool are now at 48hz.

Do I need to START OVER with the tracks unfrozen? Can I unfreeze these tracks and salvage what was already converted somehow? Any thoughts/ideas?

I would have thought I would have been prompted to unfreeze these tracks before starting the conversion :neutral_face:

THANKS!
