Default folder permission problem

I have my transmission configured to download files to “/home/osmc/Downloads”. When sickrage try to post processing a file, I get this error:

I’m already changed /home/osmc/Downloads permission to 777. But when transmission download a new file, this files gets 644 permission. Any ideia to solve this?

Sorry about my english!

Done!

It still shows the PublicHD scene group.

I think you will have more luck asking this on the SickRage forum.
