This is a bug report which has not been resolved since the launch of Destiny 2: Edge of Fate, the kill tracker on the hand cannon solemn remembrance has a bug that shows the kills of whatever weapon is in the energy slot instead of showing the actual kills of the hancannon, it seems no one is reporting it because the number of players who don't have the weapon or don't even use it are low and those that have it and use it don't know about the bug.
