Odd behavior with word deletion

In the Maori thread I wanted to do a comparison where I’d get a bunch of word glosses using context-sensitive lookups, and then Delete + Permanent Delete all of my words, turn context-sensitive OFF, and then go back in and get the definitions again.

I use “Ready to Learn” auto-highlight and to my surprise, perma-deleting all my words left words underlined. It creates a minor issue where clicking an underlined word gives no definition and no option to find a definition. (Though one can turn off the auto-highlight setting and get a definition then.)
