Can't delete spam from Gmail in Mail.app

[doobs]

I have a bunch of spam that is properly flagged as such in my Gmail All Mail folder in Mail.app. I delete all of the spam, then go to Trash and delete it from there, but it shows right back up in my Gmail All Mail folder...wtf? I cannot figure this one out...why won't Mail.app delete the spam from my Gmail All Mail folder like I tell it to do? Thanks in advance...

I've noticed that also when I changed my gmail from pop to iMap. I kept deleting them and they keep coming back. What I did was to go to the gmail website and delete them from there because that spam was also in the webmail. After I deleted them from the website they disappeared from inside the apple mail spam folder. This wasn't happening when I only had the Pop gmail which I deleted that folder to use the new iMap gmail. I know there has to be a setting somewhere on their website perhaps to correct that but I couldn't find it.
