I had only slot 1 and replace the cheat file with yours and the 3 slots work fine on mine have the 3 on 999 , but for jump i press b and does normal jump only .
If that's the case, then the problem comes from SXOS's cheat engine.
Maybe because i did use the same register for moon jump and mastercode this time, it does work on Atmosphere, but maybe SXOS is confused and overwrites the moon jump register when the master code is active.
You can try to change the register, just use E instead of F
