Not possible to choose the shipment

[Mapache64]

Hello,

I have different shipments to choose and in the BE selected "no preference". But in the FE always shows the same shipment an edit is not possible to select. Also if a change it in the BE, I only see one shipment-possibility. I cleared cache, started the browser again, deleted cookie etc.
It is Joomla 3.5.1 and VM 3.0.17.2
Any idea

regards
