Organization News banner text

Hi there, I've created two new organization news sites for two types of comms (one for CEO news and the other for firm news) but when we author news articles in those and surface them in a news web part on the intranet home site they don't have the banner for the org site name, it shows the home/hub site name. I've set the sites up correctly from what I could see using the Set-SPOOrgNewsSite cmdlet using this syntax Set-SPOOrgNewsSite -OrgNewsSiteUrl orgsiteaddress so I'm not sure if I've missed a step. Can someone help me, please?
