I don't know - last night when I tested the 2 settings you listed, the resulting files were exactly as they should have been, but I didn't test it any further. But when selecting any of the Pull Up/Pull Down presets now, some show the correct sample rate and some don't. It's bizarre because I still have the session and the file imported at 0.1% Up is only slightly faster than the original. It may be an intermittent problem.

I installed PT 2020.3.0 and all the Pull Up/Down settings show the correct source sample rate when selected so some of the settings in 2020.12.0 are showing up as the wrong sample rate. I'll report the bug and hopefully it gets fixed in the next release.

At least you can enter the correct sample rate manually as a workaround.
