Don´t know if bug or game engine limitation/sea state dependant, just wanted to let you know.

It's not a bug. RA mod uses different masts heights (like in real) for periscopes, radars, ESM etc.
You should check it in:
USNI REFERENCE -> OWNSHIP INFORMATION -> (your submarine)

Btw I've played first mission of Ohio campaign (soon on my YT channel) and all worked fine.

There are 2 random variants of partol areas. One on NE and second on SE direction. In my game patrol area was on NE from start position and message with coordinates and red asterisk were correct.
