Yes, 3 sites.
My best guess is, whatever was present at the other 2 sites/or occurred at those 2 sites - was considered best not further discussed by both sides.
India was happy to focus on the terror camp it hit (nobody in the world can have an issue with fighting terror, as opposed to war with a nuclear country), and Pakistan was happy to shift focus/questions away from whether its military had been hit.
There was later some separate talk of a Pakistani airfield being hit at Tarbela, with multiple F-16's destroyed, in a different incident (as full and proper revenge for the Feb 27 skirmish) - but that's all very murky and based entirely on speculation - though some normally reliable people did believe something had happened.
