Nintex Observer

Missing Attachments from control after uploading

I designed a nintex form with attachment control inside a repeating section and store XML in multiline text column. I noticed when I view the item after submitting the attachment that the attachment of the last row in repeating section is missing. and its not stored in the items attachments (although its showing in XML).

This happens with IE but its working well with chrome. My IE version is 11. I'm not sure about other browsers.

Did anyone face this?
