Dropped MDS schema, now cannot recreate it with the same prefix

Hi,I dropped MDS schema, ex. DEV_MDS and now I cannot recreate it with the same prefix, DEV_MDS, using RCU.
Is anyone aware of any table where the record of the old DEV_MDS is kept and needs to be deleted before the schema gets recreated?

Not that it matters, but I am using RCU 11.1.1.7.0

Thanks!
