Or should I say, I cannot see them on Broadband or Narrow-band if they are in fact mirror contacts.
For instance Broadband will only show 1 line (if for example I only have 1 contact S1), so it then appears there is no ambiguous contact for S1.

Spherical or flank arrays do not suffer from ambiguous contacts. So you must have selected the Spherical array when you only saw 1 line in broadband. That said, a mirror contact on the towed array in broadband during the course change phase could be smeared out over many pixels making them more faint in the display. Perhaps not noticeable even. But after the TA has straightened it would show brighter again on the new mirror contact bearing.
When I tried the mission just yet I couldn't get any clear line in the TA broadband display. Only on long time averaging could I see a signal. Your best tool would be narrowband in this case.
