[Not a bug] Epiphany + Nadroji +sets issue

I dont know if it is just a visual bug or what, but I just finally found my first epiphany ring, did a little crafting and equipped it. I have 2X +2 sets ms socketed and a +2 sets affix on the Nadroji amulet, and it’s showing 5 (4) in the stats page, but each of my set affixes are only showing rank 5 when they should be 6.

Epiphany don’t increase all set cap.

Poop. Ok thanks.
