In the Ultra Sun/Moon , Pokemon's Chinese names are displayed incorrectly

[Lithium-1on]

Describe the bug
This bug was found in the Chinese version of Pokemon Ultra Sun/Moon, when I used PKHeX to edit Pokemon, it caused some characters missing from its name in battle. For example, when I edit Necrozma, its name will be displayed in battle as "奈克洛" instead of the correct "奈克洛兹玛". This error is only reflected in the name displayed on the HP bar during battle, the Pokemon name will still be correct when viewing it in the box.

Some additions:
1.The absence of characters does not necessarily exist in all Pokemon, and some Pokemon names are normal. Missing characters are not always at the end, but may also appear in the middle and at the beginning.
2.I found out in some forums that existing players have also mentioned this bug, and they fixed it after using the older version pkhex, I tried version 22.11.24 (which is the oldest version I could find) and found that it worked.
3.When I changed the language of Pokemon to Japanese, I found that there was no similar problem, so I speculated that this problem may only exist in Chinese Pokemon.
