I will try to explain this issue with photos, but shortly I cannot upgrade my talisman even I have enough amount of evolution runes. I have 2 stack of 2* red evolution runes. one stack has 8 runes, the other one has 99 runes. However when I try to evolve the talisman, it only sees the stack with 8 runes. Here are the pictures.
This picture shows that I have 107 2* red evolution rune.
This picture shıows that evolve screen only recognizes 8 ones.
