Question about Kase Armour Entry Level Magnetic System Kit

hi, on the official site it says the kit has 2 step-up ring (67 - 77mm, 72 - 82mm) https://kasefilters.com/product/kase-armour-entry-kit-100mm-system but the one i got has 67 - 82mm & 72 - 82mm instead. There's no 67-77mm, which makes the 77mm holder useless for me. Can I swap 67-82mm to a 67-77mm adapter ring?
