Endnote macro's found in Word Global templates

I am trouble shooting wth microsoft word to do with normal.docm template

I  just found some endnote macros in gloabla template in word. i deleted them. How did they get there , does anyone know please.

Can I run a test in endnote before I reinstal. i am afraid of restoring my back up.

I keep getting an endnote error that “execution failed” when I am not using endnote.

Can someone help please?
