Colossal surge only gives you 21/22

In addition to a description of the bug you are reporting, please provide:

This collosal surge is a joke. I calculated it will take me $250 buying bundles etc to have enough crests to max it to do the upgrade to rank 5. Seems cheaper than buying a rank 5. But it shows I’ve obtained 14/22 but have 13/22 available toward ranking up. Counting remaining left to claim I fall one short leaving me at 21/22 and have not used them at all? I obtained a rank4 in elder so been waiting to use them all to rank to 5*. What a scam! It ends tomorrow and doubt will see any resolution in time. Glad I didn’t spend the money first before I figured out I’d fall short.
