Color Picker does not display properly in Organizer

I am trying to change the color associated with a category tag in the Organizer.  I have Elements 2021 on a mac running Monterey 12.3.1.  In the Keywords I select my category tag, then choose "Edit" from the drop down menu next to Keywords.  This brings up the "Edit Category" box, then I select "Choose Color".  The Color Picker box comes up but is distorted.  I will try to attach a picture below.  The 3 windows within the box that are supposed to display colors are instead semi-transparent.  I can see through these windows to the Organizer thumbnails below.  The windows are not totally clear - they appear to have faint colors over them, as if looking through pale stained glass.  Any idea how to fix this?  The Color Picker box displays normally in the Editor.
