Quoting in threads

I noticed a new format when quoting posts, which seems fine but I don't seem to be able to delete it in my open post if I need to change it. If there's an image with the quote I can click on that and delete it but that's not enough.

So if it's the second or third quote then I have to start completely over cuz I have to delete the entire post. :-(

ETA: I noticed the highlighted quote stays highlighted in the new post and will delete if I don't click into the blank area first. If that makes sense.
