The only problem I can see at this moment is they are not equipped.
If you are applying full back spin to them, stop. They don't need full back spin or very little back spin at all if any. In fact you may wanna try topspin at first.
The 64 wedge will back up with no back spin. Depending on other factors it can back up quite significantly. If you apply too much spin to it, it will take off back wards on your not to mention, lose some ditstance. With the 64 I usually just leave the dot a alone on full shots and if I apply an yspin it might be abit of top spin to get some extra distance or to prevent too much roll back
The 60 wedge spins back a bit less but will still back up a tad with no spin applied. So again, I tend to not touch the dot with this club and if anything apply some top spin.
Beyond the spin not sure there are any problems with the high level clevelands
