Edited syntax coloring preferences are not applied or saved

Description

What steps will reproduce the problem?

1. Go to Preferences -> Syntax coloring -> Edit selected
2. Change the color in Highlight -> Occurrence
3. Press OK twice

What is the expected output? What do you see instead?

I expect the occurrence colors to change in the editor, but I don’t see the change. When I go the Syntax coloring section again, I find that the change is lost.

Please provide any additional information below

@dandawg I finally realised that the confirmation box with ‘apply’ was being opened, just was weirdly displayed behind the spyder editor window so I didn’t see it. Maybe it’s the same for you?

Yeah, looks like after clicking OK, the “apply” window was immediately sent behind the main spyder window. This gave the illusion that it was closed. Once I found it and clicked apply there, my color changes stayed.
