your second post in (pb) had pics. sometimes attachments to a post seem to "linger" and get rolled into the new post which then gets rejected cause the files already exist in the bread. try closing out your quick reply window each time before posting a new post or make sure no attachments are still lingering from an earlier post in the quick reply window or the post section at the top of the bread.

just spitballing, not sure if any of that fits your situation, but it has happened to me a number of times.
