the fact that on top of your screen it says 2of2 doesn't mean you are providing 1 signature. for instance (i just tested this) when you create a 2of2 wallet the first step creates your key, then in second step it asks you for the second cosigner key. you can provide it with a master public key (xpub....) and NOT be unable to fully sign on this wallet or you can provide it with a master private key (xprv....) and be able to fully sign the transactions since you are holding both keys and providing 2 signatures.

The fact that watch was setup incorrectly is immaterial. You should never be able to spend from a 2of2 multisig with only 1 signature. Period.

setting up your multisig wallet incorrectly would ultimately grant that wallet ability to fully sign transactions
read pooya87's comment I quoted above,
if you mistakenly provided both xprivs to one wallet, you are NOT having true 2-of-2 multisig wallet
what you thought a wallet with 1 signature, actually owns both keys to sign Undecided
