I think this may be a minor display bug.  

If your AdminCP uses Dark Mode and you add the Commerce Overview widget to your dashboard, when hovering over a choice, it's not updated to reflect dark mode colors.

 

Thank you for bringing this issue to our attention! I can confirm this should be further reviewed and I have logged an internal bug report for our development team to investigate and address as necessary, in a future maintenance release.

 

A new version (4.6.11) has now been released which resolves this issue. Please upgrade to the latest release in order to get this fix.
