Place Tags Operating Incorrectly - United States vs United States of America

I downloaded Photoshop Elements in January, 2019 (I'm now nearly 30,000 photos in).  This version has allowed me to use the "Place Tags" properly, placing all of the US cities under appropriate states under "United States of America".  Then it began creating a whole separate list of place tags under "United States".  So now I have two lists going and doing so automatically.  Then it recently inappropriatly added 2 Texas cities underneath "California".  What is going on?  Any way to merge these two lists?  Or correct what is happening?  Any way to reorder the cities within a list alphabetically?  It seems others have had this issue with no resolutions presented.
