OK, it has taken just a couple of minutes to see it, but there are not two drafts of Your parts, there are only two views of the same draft file - so called "Multi Window"
You can see the same file name for both draft tabs.
And now the question comes up: "Why?"
Answer - I just have tested it here - You have saved Your draft template with two windows opend, and therefore it comes back with two windows open.
Just save Your tempalte with only one window and everything will be as usual!
Wow.... that was brilliant - that was the exact reason for my problems !
I hope Siemens pay you for all the help you provide on this forum, it's insane.
Thanks again - have a great evening
