I bought 16 keys with BTC on dispenser, so I got 16 keys in my Dispenser inventory. But, now it automatically sent a trade offer to my Steam with 6 keys. I don't want this. I want to keep them in my Dispenser inventory for now. So I canceled the trade on Steam, and Dispenser tells me the trade got canceled. So, all good. But a few seconds later it sends me again the trade offer with 6 keys to my Steam. It keeps doing this, it won't let me cancel this. So, I accepted it on Steam. But now Dispenser sends me a trade offer again with the remaining 10 keys! I want to keep my keys in my Dispenser inventory. How can I prevent Dispenser from keeping sending tradeoffers to my Steam?

I didn't set up Steam authenticator yet (if it has anything to do with that).
