Mirage Archer/Mirage Deadeye cannot create additional effects like ice fragments or caltrops

Mirage Archers or Mirage Deadeye (from deadeye ascendancy) can't spawn caltrops with caltrops support and also don't seem to spawn other additional projectile effects like ice fragments from Escape Shot.

They also seem to bug out completely with most channeled skills. They either never fire (plasma blast) or they fire immediately without building stages (snipe, detonating arrow) or they fire only once (detonating arrow).
