Multisig sign error

[duckien112]

Hello, I created a multisig wallet from cli. I make send command then broadcast:
./rebusd tx broadcast signedTx.json --chain-id=reb_1111-1 --broadcast-mode=block --node https://rpc-1.rebus.nodes.guru:443
Result :

I tried:
./rebusd q account --node https://rpc-1.rebus.nodes.guru:443/ rebus1t6m7k68pwne5dmspgjhv6tss4aec2zs5nuwfx4
Result:

I used command:
./rebusd keys show key1_multisig
Result:

I think nodes can’t detect multisig wallet correctly. I built from newest version 0.2.3. Maybe nodes wasn’t updated?
Thanks for considering.
