Extra text block bug?

So I’ve been having this bug over the past few years across multiple sites, so I know it’s not specific to one site.

Every now and again I’ll find some random extra text blocks appear on my site, usually inside collection items. They don’t exist as an element in the Navigator and they can’t be selected or deleted, the only way I’ve ever been able to fix them is to recreate the whole element and delete the original (not a great solution).

Has anyone else experienced this behaviour? I’ve got a read only link but will need to fix it eventually so that may disappear at a point. Here’s a picture of the hierarchy for reference.

So the “This is some text inside a div block” elements don’t exist in the navigator at all, only the “All” and “THIS IS SOME TEXT INSIDE OF A DIV BLOCK” elements actually exist in hierarchy. The only time these elements are actually selectable is when the site is published and you select them by opening up inspector.
