This is a simple request that doesn’t really need a lot of explanation. The default Rotate value used to be 45 degrees and the Move value used to be 2 studs. Now, they are 1 degree for rotation and 0.01 studs for moving. I don’t like changing that every time I enter studio so it would be nice if this could be changed back. It makes no sense to have it the way it is now because unchecking Rotation or Move essentially does the same thing as entering the two current default values
This doesn’t happen to me as it auto updates to the last increments. 
You might want to consider switching to the new UI, I assume they are not updating the old one anymore. 
The old UI did as well but it stopped doing it and idk why
Maybe try the new one, they are trying to fully push it out. Maybe this is an incentive.
If you do try the new one, please do tell me if it works! 
I prefer the old UI I do like some aspects of new UI but the old UI structure is better Imo
When was the last time you updated Studio.
I can’t remember what my rotate/move defaults were. I’d always set them for the tasks I was doing at the moment.
Is it possible your version has a glitch there if other people are seeing it saved as their last setting?
Maybe uninstall/install to see if it’s a problem on your end.
