This has to do with the order of the objects. Look at the bottom left list with objects. You can click and drag the circle item to the top of the list. That is the same as what you did without the need to cut&paste.

I knew I had created a turn circle a long time ago. Took me a while to find it. I have added it to my DodecagonBathroom library. (That's what I created the circle for in the first place.) You can change individual colors on that one.
That library has a few more models for wheelchair access you might find interesting. My kitchen libraries also have wheelchair accessible sinks.
