Electrum 2.5.1
2 of 2 multisig

I just downloaded 2.5.1 tonight and restored one wallet from a 2of2 pair.  I created a transaction using the send tab, entered the amount and the receiving address, and hit send.  Rather than bring up the dialog to sign and save, it just transmitted the transaction to the network. It now has 9 confirmations. I'm so confused... How can this happen with only 1 signature?

got it, thanks!

Hi, So I wanted to import a master pub key from my electrum 2.2.4 multisig 2 of 2 into my mycelium wallet so I could get all  the receiving addresses and easily send between my electum multisig, and my mycelium hot wallet. 

However, I copied the master public key (self x1) from one of the wallets into mycelium (via accounts/add key/advanced/scan) and it started giving me addresses that begin with 1 instead of 3.  I ended up sending some dust to the first receiving address without first confirming they were correct (bye bye dust!)  Am I trying something that isn't possible?  Do both master pub keys need to be somehow combined in order to get a correct multisig master pub key or should both multisig mast pub keys produce the same addresses?
