I have not encountered this problem lately.
You must click on the dot, not just the line. Clicking on the display so the 'marker line' covers the contact is not enough. Mark won't work. You MUST click the dot. Works for me, every time. This also affects library ID .. if you don't click the dot, ID won't show. It is same as with sub's NB display .. you must click the frequency line, not just the peak on the lower spiky line.
Also note that the dot is 3 pixels wide, and it matters where you click. 'Mark' works even if you don't put line cursor exactly on dot center .. but in such case the marked LOB will the the heading of the marker line and not of the contact. The error is like 5-10 degrees, because SB panels are so small.
All other displays marks center of th contact nearest to the cursor, but SB directional displays marks exact cursor (not contact) position. Autocrew of course marks quite exactly, but there is some visible error too.
I use buoys for ID and rough position (and I don't use autocrew). Then all I need is one ping for pinpointing the position (same way in FFG alone or Helo). I don't play P3 much, but even there I'd use active SB to get shooting solution. Passive SB lobs are just too fuzzy.
Also autocrew will mark everything passing by so it can easily clutter whole display. That's why I don't use it.
Subs are typically quite easy to spot even without clicking .. they are quiet, so you will most of the time see only the low frequencies .. surface boats are loud, so you see most of the time all lines. Use quick missions to master technique. It's fast, contact is usually close. Try to intercept it using all possible methods (for example not using helo with FFG).
