Lost Insert options: Insert to the bibliography

EndNote EndNote How To
1

Dear maintenance staffs,

I use Endnote version 9.3.3 with my word for mac version 16.42, and my Mac air 2019.

I have a problem with the Insert options. As there is no “Insert to the bibliography”. It has only, Insert, Insert & Exclude Author and Insert & Exclude Year. NO “Insert to the bibliography”. 

Please suggest how to deal with this.

Thank you
