[Battle✓] Adding new moves into Emerald gives me this error?

[Haltmann]

So I was adding new moves to Emerald with PGE's Attack Adder and when I was done adding all of them, when I went to test them in battle, my Pokémon's moves look like this.

In the summary screen, they look like this, however:

Any idea on how to fix this? The truth is, on an earlier build of the hack, this had happened too, but I don't remember how I managed to fix it... Help appreciated. Many thanks!

There might be an in−game limit on the number of moves that you have to edit in Hex Maniac Advance. It's recommended that you expand the number of moves there, as the process is much more streamlined.

PGE is known for causing problems. I recommend starting from a backup and following above advice.

Oh, that might be it. Didn't know Hex Maniac Advance was a thing, haha. Thank you so much!
