If you made any changes to an ad, the ad will show on G, but will not be shown on partner sites until it is reviewed. Never make changes to an ad, make a new one and delete the old one after the new one is syndicated.
This sort of thing is truly difficult to troubleshoot without actually seeing the account, though - so I hope that you'll contact AdWords support, who can look at your account in detail.
The most effective way to write AdWords support is to use the 'Contact Us' link, which you'll find on every page in your account.
