I’m trying to set the radio button’s default value to checked, and I’m running into a few issues.  If it helps, I'm working with an item data card, and I have two radio buttons labeled as "Yes" and "No".  As I understand it, ideally with both radio buttons set to the same variable, if I select one's default value to checked all associated radio buttons should default to unchecked.  However, I've only seen this work with one group of radio buttons on my data card.  With every other group I can select the default value of either/both to checked and changing one has no effect on the other.  Which means the best I can do under these conditions is set, for example, No to checked and Yes to no default value.  This has resulted in a 50/50 chance as to whether or not the item’s default value works properly even if No is set to checked and Yes is set to no default value.

I've checked the variable associated with the buttons that work, and it is set to text with no additional features (like Mandatory) selected.  It's the same as with the buttons that don't work.  Everything I've checked tells me that all of the groups of radio buttons I've created are setup the same way, so I'm out of ideas.

Thanks in advance for the help
