Edit old posts - troubles

I’m having issues editing one of my posts from a few years ago, here

I can edit the post but all the text is converted to include HTML tags and I’m not able to delete/add attachments. Is it so old that I can’t remove or add attachments? Do I need to start a new post?

That post was created when using the old forums, Plex switched to Vanilla around July of 2015. I would start a new post, we can close your old one if you want to start a new one.

Would it be possible to have the post deleted altogether to avoid any confusion ?
If this is not possible then I’ll like to create a new post and link the old post to it.

Thank you. That worked. I’m now able to remove attachments.
