It does depend where you are as to what the minimum milk intake guidance is. In the UK from 6 months the minimum is 1 pint or 500ml or 18 oz, all rough guides (as a pint is not exactly the same as 500ml). The bottle feeding FAQ reflects this. Which would make the amount of milk she's taking fine, plus you also add any milk/dairy solids, plus any formula you are adding to solids. It all counts. So if she takes an oz or so of cheese this counts as an oz towards her 'milk' intake too.
I found with mine the more dairy solids he took the less formula he took, so if I cut the milk products in his solid food he took more from a bottle. However if I cut any other solids he did not increase his milk at all, not a jot, he just got very very cranky.
It's also fine to have water with her solids meals.
