Grey box around blocks of text

This is almost certainly a user error issue because I’ve never really learned the nuts and bolts of Scrivener. For some reason there is a grey box around parts of my text and I’m not sure what I might have hit fumbling around the keyboard. I’m assuming I activated some keyboard shortcut inadvertently but not sure what it is. Thanks, appreciate the help.

Probably an inline footnote. Possibly the anchor for an inspector footnote.

Edit -> Insert -> Inline Footnote in Scrivener 3. If that line is checked, uncheck it to make the formatting go away.

For Inspector footnotes, make sure the Inspector is open and click on the speech bubble icon in the row above it.

Thanks so much, appreciate it. It was indeed the Inline Footnote.
