When using Compare, when finished there 2 always 2 photos selected

Recently trying the Compare feature, and every time I finish Compare, lightroom has 2 photos selected in the bottom strip.  I click the X for the least liked photo, until clicking X keeps showing the same photo, that indicates I've complete the compare.  But there are still 2 photos selected.  When I click on Loupe View, there is still 2 photos selected. Why is it not only selecting my favorte one?

I have 14.2  Windows

thx
