Can Only Attach Network Files in Forum posts, not group files

Can Only Attach Network Files in Forum posts, not group files

Hello,

I created files for groups in my files area of zohoconnect.  When I try to upload a file in forums, it only pulls up network files, not group files.  The group files are not included in network files.  When I click on attachment in a forum post and choose "from files" and then try to choose a group from the dropdown, it does not show any options.  When I try to choose a folder, I just get a spinning wheel. 

Is there a way to access group files from forums so that I can attach one in files?  

Thank you!
