Warning! I'm raising a ticket on this but please check your own installations for this issue (and confirm / deny here would be helpful!)
In instances where I have Radio Button options and have set a default value.... when it comes to the CSV data export, if the user didn't change the value from it's default then nothing shows on the CSV data.....
This isn't a CRITICAL problem because I can work things out (annoying but possible with the logic blank = the default option) BUT could be a concern if limits are applied to that default option and the selections aren't being registered properly by the system.... eg Large T-Shirt is the default BUT there's only 10 of them... Does the system know when 10 are selected.... because the CSV export doesn't!!!!)
