The "+" at the end indicates presence of extended permissions.
What getfacl says?

This is true, that Cygwin sets permissions in a non-canonical order, but
that's the only way to have desired results for certain cases of POSIX

What is "progd" ? Did you mount some directory into Cygwin tree?

Probably because of interpretation of the original Windows permissions.
