More than One References Headings

HI

My work flow is as follows

all references are stored in end note 

i am wiriting in word and using the plug in

i go to insert citations, pick the reference and it is automatically inserted

however when i open the word file again and follow the same method it creates a new reference section 

see image below.

I do not know how to find the section suggested, is it in word or on end note online?

how do i find this section to turn off the creation of new references each time?

thank you for the help so far.

Brian
