Favorites popup menu displaced

[DonnaPaul]

System: Windows 10

Browser(s): Firefox, Chrome, Edge

For all the above, when I have TV Listings showing, and move the cursor onto a channel, the "Favorites" popup appears 2 channels below . Thus, I can't toggle the favorites.

When I move the cursor right, of course the popup disappears.

When I move the cursor down, the popup follows, but still 2 channels below!

Help.
