Looking at the card details in the Event Gacha is how I found I had two cards for this event that needed leveling up but I suspect I have cards from previous to this event that need to be leveled up as well.

I have N1.32 X R2.63 X SR 1.0

I have Manaka Taneda R currently at Lvl 73
Kanami Kazaki R currently at Lvl 41
That probably accounts for the R but I do not know where the N and SR values are coming from. Neither show girls I have in this event gacha so I assume they are from past events and I may still need to level them up.

I have been doing things the slow way trying to search on every card name but cannot find any information on which cards might be them.
I have also been trying to update cards to levels that are multiples of 10 to see if the above values increase but so far have not found any.
Have there been SR cards that were 1.0 at max level?

Thanks.
