Imported course created in Articulate STudio 09 and file names changed to include {} in Story_content

I imported an existing course created in Articulate Studio '09. It runs OK when I test it locally, but when I try to copy it to my internal SharePoint site, a number of Engage interactions and .jps won't copy. When I look inside the Story_content folder, I see these files that now have {} in their file names. (See attachment for screen shot)
