Did you choose Speed Up (Jake's technique) or Hit! (Estela's technique) in Chapter 13? It's just that those choices (which are part of a timed choice) give you relationship points with whoever you chose for their technique. If you didn't then it's probably likely that they don't deem you well-trained enough given the other two options in each of those timed choices don't have any effect.

I only say this because whenever I go with Jake's technique and select Speed Up in Chapter 13, then fight and select Attack in Chapter 16, there is no effect with Jake/Estela and I get +2 Diego so it works for me.
