Duplicate Delete of Attachments in temp. threads before creation

[hcmagix]

If I create a thread an put a attachment in this I cant delete them when I put the false attachment.
I have create a new thread and attach a picture. In the preview I saw that was the false picture. I klicked on delete an get the Message that not allowed for me. I must cancel the thread and try again.

Is that a bug or permission settings?
