Maybe the front derailer just isn't set up properly to make trimming adjustments as front derailer adjustment can be quite finicky. Sometimes I find that I was in the lower trim position all along so what I sometimes do is to trim UP first just to make sure I was in the upper position before trying to trim down.

This is the exact problem I have. I have a triple front Chainring. The half shifts work perfectly in the middle ring to help with chain rub. But whenever I attempt to half shift on the large ring it just hops down to the middle ring instead. But my bike is brand new and will need adjustments for cable stretch anyhow. So I am leaving it alone and will have them take care of that when I take it in for adjustment.
