Dynamically checking grouped checkboxes

Greetings -

I am working on dynamically checking a box that is tied to a group and it does not appear to be working.  Basically, there are three options tied together that are inclusive to each other.  No matter what I have tried I cannot get them to check.  I have encountered no issue checking individual boxes, just grouped checkboxes.

md.Form.Fields["chkSomeField"].ChildFields[1].Value = "Yes"

If it makes a difference, I am currently using the trial form of the assembly found in Nuget.

Thank you,

Hello,

We have not seen any issues with checking the checkboxes. Could you please send over the source PDF and the code you are using to our support team so that they can look into it further?
