Hello and Welcome to OpenStreetMap!
I think something went a bit wrong here - you accidentally changed the whole industrial area as a shop.
Please try again, and just add a point where your premises are.
Also, I'd suggest that you don't use a spammy description when you add it, as people might think it's spam and remove it :)
Best Regards, Andy
