Cannot Get Selection List to Update

We have raised the prices on our memberships to $25 – individual and $30 – family. I went into my form, selected the dropdown where those options are listed, and changed them to the new amounts, then saved the form. However, when I load the page in any browser, the form shows the old values. Am I missing somewhere else I need to make that change?
