Not sure if these are bugs or I have disabled a setting within ROBLOX studio.
When selecting Part A then duplicating the part the selection box doesn’t transfer over to the duplicate part meaning if you want to change the colour of the part that you have duplicated you can’t since it’s changing the colour of the other part.
When you are trying to delete a part that has the move, scale or rotate tool on, it doesn’t get rid of the tools instead it stays there and doesn’t disappear.
