I have an arrowhead that has new growth but some of the leaves are turning yellow.

This can happen for many reasons. Arrowhead ivy does have a tendency to have outer leaves die off some. If it is one or two, you don't need to worry much about it.
If it is more than a few leaves, I would look to how it is being watered. It should be watered when the soil is dry to the touch on top and it should have good drainage so that it is not sitting in water.
