If you do not choose a nick for Voice , HOP, AOP, SOP and Founder then it will give you that op in all channels where you do not have but could get it based on your level of channel power.
Ex: I am channel owner. I click any of the power buttons mentioned above and it will give me the ops.
When testing it I clicked the one for SOP and AOP and as Owner in many channels it gave me +o and +a in every channel in which I was owner.
