Forum:Where To Place Episodes With Two Arcs

I was browsing the wiki, specifically the story arcs and noticed there are some episodes that has significant events which end a previous arc and also start a new one like

Episode 41 - between Tower of Heaven arc & Fighting Festival arc Episode 69 - between Oracion Seis arc & Daphne arc And the most recent one Episode 151 - between Key of the Starry Sky arc & Grand Magic Games arc

Because of that, gonna ask, what arc should the episodes be in? Shouldn't they be in both arc templates since well, read what I said above XD.
