[1.20.1, 2023.4] error: level has private access in Entity (NOT A DUPLICATE)

 When I try to build my mod, 2 of my 6 dimensions have the error in the title. I have no idea why the error is involving dimensions and especially only 2 of them, that are very similar to the rest.

I saw this error with entities in the previous version of MCreator, due to Geckolib, which turned off, but nothing happened.
