TOC contains "Contents" in Mainfile document / DRAFT-Background without using package

if this question has already been asked, just let me know!
I seperated a big document into smaller files and my table of content displays "contents" as the first entry and I want to delete it. I also have a draft watermark in my whole document without using zhe package for it? Heres a MWE
