Crystaline aura buffs not applying into song of return

it has been months like this, and i havent heard anyone adressing it
"-50% cooldown on song of return " and the base time for song of return is 60m, it should be 30 min but its not applying. its getting tired running out of bifrost and waiting way more than i have to because of this.

Base is 120 min. 50% is 60 min

lol i had no idea it was 120min base, maybe is bc i have aura since day 1
