As a mod I'm unable to remove a post with a wrong hashtag by another user

There is a comment with a wrong tag http://talk.chimpandsee.org/#/subjects/ACP000bcdh (the 2nd one from the bottom, by user Dana23) I'm unable to remove as a moderator. Browser console is showing an error. I tried to remove this post a couple of time during this week but it has never worked.
(I remember experiencing such a problem in PW and PP a year ago, not sure whether it was solved somehow. There were even comments posted by me I wasn't able to remove.)

To make things clearer, I am unable to remove just that single post. I can remove others without a problem.
