In “Only a Woman Can Take This Sort of Abuse”, Manshoon forgetten stasis clone spell FOREVER. Did it included all his clones? No. What happens to one Manshoon affects only clones of that Manshoon (i.e. THAT Manshoon's subsequent uses of the clone spell), not any existing clones. They all have different memories, spell mastery and rosters, and powers.
