Two points dropped at home against Everton (and we're through to the next round of the Carabao Cup)

Why do we nearly always go a goal behind? One-nil down after 24 mins. We did hit the woodwork three times and had loads of chances so deserved more that the one point we got after Janelt's equaliser in the 84th minute. Last Tuesday we beat Colchester 2-0 at their place in the Carabao Cup with Lewis-Potter scoring his first goal for the Bees.
