Also, 2.1.55 beta messes up the presets! It uses the wrong one.
I open the profile in 2.1.54, deck presets are correct.
I open it in 2.1.55, and Enhance Main Window shows the correct preset, but once I open the deck options screen, I see a wrong preset. And I can confirm that Anki does indeed use the wrong preset because it follows the wrong preset’s setting of mixing new cards into reviews instead of the correct preset’s setting of showing new cards after reviews.
