When I click on tools, the drop down menu shows multiple
listings of the "Mail Merge" option, literally 20, but
this is a feature I have not used (to my knowledge).

I believe that these are somehow being created every time
I create a letter.

I do the following steps:
1. Click on Tools, scroll down and select Envelopes and
Labels.
2. Fill in the Delivery Address and return address as
necessary.
3. Click Print.

Perhaps I'm doing something else to create these "Mail
Merge" additions in my Tools drop-down menu, but in any
situation, I'm searching for a way to get rid of them and
prevent their future appearance.

Thank you for any tips you can provide.
