TOPIC: Multiple Registration Cart does not work

I have set my system to multiple cart but I just found out that I can only add 2 tickets. Every extra ticket will delete one (earlier I think)

I have my setup with 0 minimal registration and "blank" at the maximal registration. This seems like a bug to me. I use the latest version and also the new Joomla.

Does anyone uses this cart system?
