How to properly cut file permissions?

Question

Access rights

Actually the question is this:
There is a file server on which there are several network drives. One of them, which maps to all users, has several folders that only certain groups of users have access to.
The problem is that new, newly created files only open on the computer they were created on.
If you manually specify permissions for them, and change the owner, then the files open, but this is a palliative. To tell the truth, I cannot understand, in what party to dig to resolve a similar situation.
OS -Windows 2012R2.

After changing the owner, only the System user has rights.
