Customer can't see queue

[ThomasPL10]

Hello

I've got some problem. I've created a new queue Queue1 connected to the group Group1. I've added Group1 to Customer Default Group - CustomerGroupAlwaysGroups and Queue1 into "CustomerPanelOwnSelection" in SysConfig. Unfortunatelly I still can't see this queue on my list on Customer Interface. I copied names so I'm sure there is no misspelling and I don't have any ACLs which could have an impact. Do you maybe know where I should also look for.

Thanks for any ideas.
