Those schisms I referenced were not over administrative authority - they were all doctrinal.
The Acacian controversy was an episode in the Arian heresies. Pope Damasus (not Damascus) had to contend with an anti-pope. I don’t who Victor and Stephen of that era are.
Patriarch Photios is outside of the patristic period completely.
I still don’t uinderstand what these people contributed, on either side, to the consensus patrum.
