I have many workbooks with several pages in them

for the very first time I have a problem

I have one workbook that when I open it I get two copies of it

in the window when you look at it you see

worksheets1200:1
worksheets1200:2

there is only one copy of this worksheet
why do I get two copies when I open it?

HOW do I change this to the normal one copy only?

I do not what two copies

I can close one copy and the other one stays open to use

if someone can tell me how I set it to open two copies
I would appreciated it

also please tell how to get it to stop opening two copies

thanks
