put an evo on my Become immortal card midway thru upgrading, now cant put 90-91

went with 85 daghim and was doing fine til i noticed mine was still an 88 when doing 90-91 boost. i thought this was weird and checked out fut.gg and it said if i added gladiator evo then it would be at a 90 and then i could add 90-91 boost. it was able to add originally but was boosting to an 89 not a 90-91 so i wanted to max the card out as much as possible. did the gladiator evo but now the card isnt a become immortal card 😐 so its capped at 89 and i cant even use the 90-91 or 91-92 on any other card cause the 88 boost is still in my daghim. please help, this promo in itself was very confusing on the order to upgrade cards and lots of people i can see form other comments have their cards capped at 89-90 due to this. please assist
