Introducing devlogs

Oki. I have a small question.

Like you see in the image, I have a LOT of Files inside my Devlog “Add Attachment” part.
This is because I tried out using the itch.io butler to upload / update the files of my game and every single file, was it’s own butler push.

So, here my question, is there a way, to remove those files, I don’t need anymore? And is there a way, to prevent the butler from doing this?
Would love to get an answer!

Thanks!
