Question: How to remove "Comment deleted by author" in MaplePrimes?

In a recent MaplePrimes question: https://mapleprimes.com/questions/240543-Maple-20251-On-Windows-11-How-To-Resize 

a discussion of interrupting a computation also came up.

I gave some comments. In one of these I wanted to include a link to a screenshot. 
I tried several times. It seemed that I only had the choice between the full image or a thumb nail.
So I chose the latter. That appeared to me as worthless. I tried a couple of times more, but decided to delete all 3.

Then I wrote a comment without a screenshot. 

It looks silly to have these empty (and anonymous) "comments" still around.
Is there any way to remove these?
