Pokemon illegal/don't understand the cause

So when I made this Magearna in PKHeX (7) it gave me the error "Invalid: Can't Hyper Train a perfect IV" and I have no idea what it means/why I got it.

The error message literally tells you the problem.

You cannot hyper train a stat that is already perfect.

how can I solve this?

Shift + clicking on the stat applies hyper training, and shift + click on the stat again removes the hyper training.

It worked! Thank you for the help.
