When i change chapter in Playback > Chapter the toggle left of "Chapter X" changes to the one i select. Like i would expect.
But if i detach the Chapter sub menu by selecting the - - - - - line above "Chapter 1" and then change chapter (in the detached menu), now the toggle comes on when i change to another chapter, but does not go away from the other chapters.
If i select a chapter that is toggled on, it toggles off.
The chapter that was active when the sub menu was detached is always toggled on. If i select that one it does not toggle off.
If i change chapter from the Playback > Chapter sub menu (when the menu is also detached), then the last two selected chapters is toggled on (in the detached menu), unless i select the same chapter twice, then only that chapter is toggled on.
