Bets disappearing?

I just started today and have activated alerts, that means I place the bets like instantly after they show up.

But why do the bets disappear so quickly? Should I not place the bets if they disappear from the interface?

It’s a setting (that reduces variance). The bets that disappear are on the same match, if you were to bet on multiple markets within the same match you would get even more swings.
If you for any reason want to change it (I don’t recommend if you’re new and don’t understand it), there is an option in the settings menu.

Ahhh, thank you very much!
