To clarify…
This is what mine looked like.
I still don’t know enough about plugin coding to speak with any authority, but my case may be related to the
Clean Up Notes plugin. (?) I had run that first (to delete the leading blank lines), because it destroys the rich text formatting; and then ran
Move Note URL to Rich Text Web Link. The result was as in this screen clip.

As I said, these were easily fixed.
But I experimented on a test DB. I duplicated the above. But simply running
Move Note URL twice not only ‘chops off’ the “h” in “http”, but loses the rest. And the rich text coding is misplaced?

I don’t know if my experience is a clue, or just another point on the curve.
I don’t think it’s a high priority to “fix” either of these plugins, but they are both
very valuable tools for us FTM refugees. (I know how to use them now.) They’re probably useful for others, too.
