Rank up gem not showing up

I have a rank 3 human torch and two 3 to 4 rank up gems. And it isn't coming up as an option.

Please read the pop up first...HT is not a 2017 champ.

Oh God damn it. Bogus. Thanks.

Read the description of the gem... can only be used on champions 2017 and older

Oh God damn it. Bogus. Thanks.
