Active endpoints but network shows no containers

Hi All,

I am trying to delete an overlay network but receive the error about active endpoints.
But when I inspect the network it shows no containers.
Can someone point me in the right direction as to how to remove this network?

Thanks

Ian

Here is my docker info and the results of trying to delete the network.
