Watch crew on deck while submerged
 

Is there any way to fix this?

If I lower my attack periscope I can see my watch officer standing on deck at peri depth...tried exit/reload, nothing works.

Not sure if this will cause problems but it bothers me...

I do know the mega mods do. I'm not running one of them yet but my watch crew does disappear when submerged. Tho I'm not sure which mod cures that.

I believe the mega mods also show the watch officer climbing down into the con, and he then disappears until you surface again.

Try to enable MightyFine Crew Mod
I'm sure it can fix this issue..
