Manual Synchronization includes dont show up

i want to use the Manual synchronozation includes feature and im adding:
scm-sync-configuration/checkoutConfiguration/.git/config 
and another one 
scm-sync-configuration/*
(because i want the .git/config file of scm-sync to be synced because it includes the git creds)
but i cant see that those files are being copied to the github project.
any help please?
