I have the same problem.
Played through whole CnC1 without problems though. All progress saved and bonus contents was unlocked properly.
Settings was kept on restarts.
But when I started with RA no progress saves, settings changes to default everytime I start the game again.
"Mission select" is empty as I haven't played at all, although I've done about 5-6 missions on allied.
Jukebox settings is kept during a restart though.
/edit
I'm playing on Steam
This solution helped for me.
It seems my cloud save was full for this game. I unchecked it in Steam and cleared some space.

Dunno if it's important, but I also removed the file "Player_RA_settings_1.bin" in my Steam folder.
It can be found in "...\Steam\userdata\271031\1213210\remote".
It will be recreated once the game launches again.
This helped with Red Alert, I've seen people having the same problem but with TD also.
I guess it works the opposit way then.
Gave it a try and it works perfectly!
Thanks!
