Pan-demic

Why does this happen?

What should I do then? Should I sell it on backpack.tf or some other website. IF then, what site should I use for selling this?

New trader here. Im having a crap ton of fun with this site and I sold a mercanery grade star crossed iron bomber skin that was factory new on a auction on this site. It didnt work and I just wanna see if anyone is intrested in my skin. Im also accepting any advice people can give me on selling this weapon skin for profit.
