Technical Details on product page

Hey guys! I’m new to FBA therefore please assist me a bit. I want to sell duvet cover sets, but it always asks me specific (mandatory) things like Thread count , height of the article etc , which are never visible on any other listening from competitors. How can I hide certain information from this „technical page“ part?

I mean, I can understand that the size of the bedsheet duvet cover is important but why things like article height or thread count (never saw that) somewhere else. It’s microfiber so I don’t even Know the TC, only GSM ….. it’s currently blocking me to create the listenings.
