Social security disability, first case denied, second approved, both remanded from appeals council?

i filed an application for social security and was denied on appeal. my attorney immediately filed a new claim and it was approved within 6 months on the first attempt. he also appealed to the appeals council on the denied claim. now both claims have been remanded to the same district where the first claim was denied and he said my benefits could be revoked since they are now ruling on both claims. when ss approved the second claim, they cited "overwhelming new evidence" despite the fact i hadn't seen a doctor or had a new test done since the first application's appeal hearing, which had been 6 months prior. has anyone ever had this experience and what was the outcome?
