Custom fields don't show up after being created in studio

I created 2 modules from module builder.

For one module, whenever I create a custom field, the display name automatically gets changed to LBL_(display name):
Even if I try to edit it afterwards, it gets saved as LBL_(displayname).
None of these custom fields work in Layouts when I try to add it to edit, detail or list view.

For the second module I created, I can create custom fields in the exact same process in Studio and it gets created and deployed with no issues:

Why is there a difference between these two, and can I fix this through Studio as I don’t have any experience with php/coding?

Can you check the permission for the folder custom/modules//language ?

It was our permission settings so we just got it fixed, thanks for the reply!

Glad that it works for you!
