Permissions not being inherited

Hello guys,

I am currently having some problems with my files regarding permissions. When I copy from my windows through samba some files, some of them are copied as follows:

But that is not the confif I have in my OMV:

So it is very usual, that I need to constantly apply again permissions recursively to the whole shared folder, because they are not correctly inherited.

Any idea why is this happening?

Kind regards
