Split Burn Speed Setting is not retained, or, if it is, it’s an undesireable “Feature” change.
Every Burn on a Split is preceeded by an annoying “Speed Selection” pop-up, and Checking “Save as default” doesn’t get rid of it.
“Recommended” has worked perfectly for me for 2 years. I would suggest if you want to provide a “Prompt” option, add a Check Box, or add it to the Drop Down List as alternatives to annoying everybody else.
Clone doesn’t have the problem, so it’s probably a Glitch.
