I have a Nintex Form (ver. 2016) that I have set up on a completely non-fancy SharePoint (2016) list.
On the landing Home Page of the site, I have the form being displayed as a Web Part. I can submit things fine to the form, however, if I upload an attachment using the Web Part form, it will format the ending attachment file (in the attachment table) with a comma followed by whitespace.
If click on the list item and copy the text of the link, when pasted into an editor will show something like "testFile.png,Delete".
I have included a few pictures to show exactly what behavior I'm seeing. I have tried several different attachment files from various sources, and the results are the same.
Can anybody else reproduce this problem (or tell me how I can fix it)?
