Custom Models for Moss Carpet have errors and inconsistency

Transparency doesnt work anymore with normal Moss Carpet since 24w40a, but it does work for Pale Moss Carpet

However, Culling doesnt works for Pale Moss Carpet, but it does work for normal Moss Carpet

so, for example i have this custom model for moss carpet since a long time ago, and it stopped working recently, as you can see, the model has culling for the "grass/moss trim" to appear only in the edges

OBS: THIS IS NOT A SUGGESTION ASKING FOR SOMETHING NEW!!!! IT USED TO WORK PERFECTLY TILL 24W40A!!!!!

EXCEPT FOR THE PALE MOSS WHICH WAS INTRODUCTED RECENTLY AND IS INCONSISTENT WITH THE NORMAL MOSS CARPET
