“Certificate already generated” but it has expired

Hi folks. I have a site that has used WordPress / Really Simple SSL for years. The last few times I have manually updated the Let’s Encrypt cert within 90 days via the Really simple SSL / Let’s Encrypt wizard.

This time, however, when the wizard gets to the Generation stage I see this output:

•  Terms & Conditions are accepted.
•  Successfully retrieved account
•  Certificate already generated. It was renewed if required.

If I copy the generated CRT, my web host tells me it is ALREADY EXPIRED. It looks like Let’s Encrypt is returning an expired cert. It occurs to me now that perhaps I should ask for help on their forum. But if anyone has an idea how I can proceed that would be v v helpful.

Thanks
