All Product SEO Lost 4.0

Good afternoon,
After years of using your plugin we’ve just updated to 4.0

I can’t believe my eyes!
It appears that we have lost all our SEO titles and descriptions for each of our individual products that we’ve worked on over the past few years.

Please tell me I’m missing something obvious.
Every product is now assigned the title & description of our shop page.

Look forward to hearing from you soon.
Kind regards,
Mike
