New files created by my application not inheriting parent group name

In my linux machine, I have set group permission of parent folder Node1 using chmod g+s,
drwxrwsr-x 2 root fsync 4096 Jun 27 17:40 Node1
But some of the new files (not all) created by my application inside, folder-Node1 are getting group name root. (My application is written in C and runs as root. It uses fopen,fwrite to write to file). Why is it not inheriting parent group-fsync ?
ls -l Node1 gives below result
-rw-rw-r-- 1 root root 6.9K Jun 27 15:28 180906,163151896,IST,P047,Node1,Kalkitech.CFG
-rw-rw-r-- 1 root root 107.5K Jun 27 15:31 180906,163151896,IST,P047,Node1,Kalkitech.DAT

it's possible the file is initially created with the fsync group and then your application changes the group. Or the file is created outside of Node1 then moved there (thus not created if on the same filesystem, the group won't change). Could be debugged with strace on the application or perhaps with inotifywait on the directory.
