If OpenSea shows old details for your ENS name, such as the wrong expiry date, image or avatar, refresh them from OpenSea. OpenSea runs its own site, so ENS can't do this for you.
Refresh your name on OpenSea
Go to your name's page on OpenSea: opensea.io/ens/ followed by your name, for example opensea.io/ens/yourname.eth.
Select the ⋯ menu under the name, then Refresh Metadata.
Wait a few minutes, then reload the page.
