Error with creating Certificate Authorities

[socday]

When running I get this error
./network.sh up createChannel -ca -c mychannel -s couchdb

ERROR: Network "fabric_test" needs to be recreated - option "com.docker.network.enable_ipv6" has changed

I try to fix it by changing the network name in compose-ca.yml and I won't get that error. I believe because the createOrgs() that calling this ${CONTAINER_CLI_COMPOSE} -f compose/$COMPOSE_FILE_CA up -d 2>&1 in line 225 and calling it again in networkUp() inline 313 which calling compose network again.
After that I get orphan containers. I'm not understand docker enough to fix this.
