Using Gnosis in combination with Multi-Signatures and Ledger

Hey guys,

I have a problem using Gnosis Wallet in combination with the ledger and a Multi-Signature Wallet. Using Gnosis with the ledger works fine. The problem is that when I am setting up a MultiSignature Wallet, I confirm the transaction with the ledger, so far so good. But I never get any notification in the metamask of the connected wallets? Where do I confirm them? What I have seen in some tutorials is a pop-up in meta-mask, but that never happens.
I hope you got the problem and know what I am doing wrong.
