If you are sure the lenses are fine then I would say it is an exposure problem.
The Tessar has only six glass/air surfaces and multicoating doesn't improve contrast that much on this type of lens. Damaged coating on the front element isn't a big deal. Uncoated pre-war Tessars perform very well.

That's very likely. With a fine camera like a Rolleiflex you should invest in a real light meter. Take another test roll with the Rollei and use the OM-2 to meter the light. Don't forget to set it to the correct ISO!
