Maybe better not to jinx it. My meter is working accurately and I hardly ever use DOF either.
To be simple, there are two possibilities.
1, it was assembled with the mechanism not properly connected. So everything is in there all set, all clean, all moving smoothly. All that is needed is to position the blade tabs properly with aperture set properly and put the side panel in position (for F, with shutter speed and aperture properly set, ASA dial properly set, then install meter block with proper setting of its lever).
2, there is something off somewhere in the mechanism itself and you get to trace out the problem along a pathway of maybe 8-12 or more parts that are underneath the ASA mechanism in the side, and turn corners to connect to the shutter block. This can mean removing the lens shroud and possibly the lens board (with all the attendant fun of doing this on an F). Can also mean disassembling the focus knob to clean up the indicator vanes themselves.
If you want to have everything working and you are willing to have to learn more than you might have expected about the internals of a Rolleiflex, go for it. It isn't difficult. But it is demanding. I would be prone to suggest that it's the kind of fix that is best done when there are more pressing reasons to go in and disassemble the side and lens boards.
