Hello, I am trying to figure out how to fix the issue i am facing on my nintex form. 

I have a multiple selection checkbox with two values (A and as my list item. I have created a workflow which works fine, however, when i first fill in the form and check both A and B and submit it, the values disappear and both checkboxes end up blank. When I select either A or B, the form saves it just fine and displays for the user to review. 

If there anything i can do to ensure that both A and B are visible once i submit the form? I am not sure why this is happening.
