What's this blue highlight mean?

Hi.

Looks like you have changed the background color for those command chips, just select them and click on the "Remove formatting" button from the toolbar, and they should get fixed.

This happens to me as well and I am positive it is not because of changing formatting. I need to completely delete the affected text then write over it in order for it to be rectified.

That's what I did to rectify.
