Rental Property: Switching from "Use IRS Method" to "Use Tax Court Method." When I click on Use Tax Court Method nothing happens. It won't change. How do I do this?

I'm on the "Allocating Interest and Taxes" page for a rental property. I can click on the Tax Court Method button but it doesn't change anything. When I leave the page and come back it's gone back to the IRS Method.  What do I do to make it change to Use the Tax Court Method?
