Endnote Bibliography: wrong value?

Dear community,

Im almost close to get crazy, may someone help me?

I started working with Word 2015 for Mac and endnote 7.7. When I wanted to Insert a citation, no problem. It was also possible to change the Style. But whenever I wanted to configurate anything in the "bilbliography, this error occured…(see screenshot) No matter what number I inserted, what style I chose… I tried every option, its simply not possible to push “OK”…

Can someone help me?

what build of Word?  15.22.1 fixed a com out of range bug I remember.  http://community.thomsonreuters.com/t5/EndNote-General/Attention-X7-Mac-and-Microsoft-Word-2016-users-Word-version-15/m-p/129693#M24680
