I hate gels title

So……..

I am trying to get this title in tales of symponia

And I have just beaten Pronyma and have not used a single gel on Genis or any orher party member and I have had genis in the fight aswell but still couldn’t get it to pop?

Any ideas why this might be?

I will add I have healed at inns and had kratos/raine use healing magic

The only thing I can think of is that with the party set to automatic one of them may have tried to use a gel?
