I opened my inventory and bought item on dispenser, I paid my tf2 keys for that item. But I cannot see any item in my shop inventory.
It records in my market order tab that I bought items at some shop, but there's no show in order history tab.

I bought 5items maybe(I have not really remembered it but I calculated amount of paying tf2 keys for those items, perhaps it's correct even)
Anyway first they were in market order tab but not see in my shop inventory. a few hours, they showed up in my shop inventory and bot sent me a trade offer every 15min and then they disappeared in my shop inventory. I'm so confused with this bug.
