Reviewing my red ale recipe

Observation I’ve done two batches of the red ale (which I wrote up one run-through of) and I’m pretty happy with the flavour, but one thing that has vexed me is the quantity. I ended up with about 17L of beer at the end of the last batch, where I was expecting something closer to 25L.  Hypothesis I think that if I play with the Brewer’s Friend website, I can increase the final yield without altering the flavour too much.  Method I entered the ingredients used in the last batch into Brewer’s Friend, as shown below.
