The message below solved this for me. (I know it’s a very old thread, but this could still help someone.) To paraphrase:
If you have accidentally double-highlighted some text, then to remove the highlighting, quickly tap the text. If too much text gets selected, then deselect it and try again.
You should get a large window that says “choose highlight”.
In that window, you’ll see each instance of highlighting. If there are many, you may have to scroll.
Tap on one instance to select it.
Then you should get the smaller menu with the option to “delete”. For each time the selected text was highlighted, you can repeat these steps.

I think what you're seeing is the "Choose Highlight" screen that let's you choose between overlapping highlights – if you have more than one highlight over the same word(s). Instead of holding your finger on a highlight to delete it (long pressing), you should simply tap on the highlight. Long-pressing on a highlight will create a new text selection, instead of selecting an already-existing highlight, and may lead to the creation of several overlapping highlights.
