Shared Group Opens in Browser


I have shared a group with a group of classmates and one of them has issues where the desktop version of endnote20 is opening the group in the online browser. On his desktop version it shows up under “groups shared by others” with the “email-Group name” format and when he clicks it, it opens in the web version. However, the other groups members and myself have just the group name listed under the section “my groups” and everyting is within the endnote desktop software and not the onine version. Anyone know how to keep it from opening in the the online window?
