OnSerialize and OnDeserialize calls write the same amount of data error.

Hello everyone.
I have following errors using Mirror Networking on Unity 2021.2.8f1.

There isn’t these bugs in origin code, but I have when add some assets.

This is origin code.
But if I insert new item in CustomizeInfo struct, these bugs occurs,
If anyone has any idea why that happens, or if I can do anything to avoid that, then please let me know.

These are my bugs and code.
