Can't transfer my NEX from O3 wallet

I have tried to transfer to a nash exchange address (NEX) but it doesn’t let me send it! is it because there are transactions ahead of me? Attached there is the image below!! I really don’t know what to do!


you only can transfer your nep-5 assets to Neo address (started with ‘A’)
and If you don’t have GAS you can not add the priority fee
