ActiveX Option Button On Click Formatting: Can It Be Controlled?

I'm running into an issue with my ActiveX Option Buttons where they change appearance on click, rendering my transparent settings moot.

Here is an example of the process flow where a user decides to select 'New Visits' instead of 'All Visits':

After click

Here are the properties of the buttons:

Is it possible to avoid this scenario?
