Pl open an SR for this with Support.
I would suggest you take a backup of the temp tables and drop them.
If the fixes delivered are verified to be be correct and you were able to close and reconcile the periods then you can just drop them after taking a backup as suggested by Srini.
GDF backup table name end with BKP thats one thing i know
If you already know GDF patches applied you can get data driver table name from readme you can use part of data driver table name to search backup tables
For example patch 17445609 has data driver table AP_TEMP_DATA_DRIVER_12747980
so backup will be %12747980_BKP
Or you can go to GDF fix script output and get backup table names
