I found out she was first listed in the St Herman Calendar, and they gave a reason for her listing as a reminder to pray for her on the anniversary of her repose, which also applies to the other departed righteous ones on their calendar. I'm guessing all the other names listed in your calendar should be double-checked against the St Herman Calendar to make sure the distinction is somehow made for those righteous ones meant for commemorationof the departed at the liturgy, probably with their names in italics and a footnote explaining it.
