How to stop double click in edit from requesting link location dropdown

I recently reinstalled Thunderbird. Ever since then I am having a frustrating issue that I never had before. Whenever I edit an email which was saved as a template and I double click a word with colored font to change it, a dropdown menu pops up asking me to add a link location. I added a picture below. I would like to turn this off. I do not need to add a link location to the word. I am simple editing an email. I use templates, so I often have to double click a word and replace it with a new word. I highlight these words with colored font so I can find them easily. I do not need to add a link. This is adding a extra step that is making work much more difficult. How can I stop triggering a link location when I double a word while editing?
