Frequently bought together shows in frontend but not backend

Hi,

I had the plugin working fine, but now experiencing issues.

I am using the latest version.

If you go on this product listing, https://bit.ly/3rOAj9k, it will show Frequently bought together showing.

However, in the backend, the products selected are now not showing. See here: https://prnt.sc/9xht5ccs-y-1

Can you please help show them in the backend?

I have changed no settings at all. They were set fine in the backend https://prnt.sc/6wmbXHODQIQM

I set 4 products for all 7 pages of products and now they have all gone. I just set one now: https://prnt.sc/1JBhdhZaa3y5

It took me 16 hours to add each individual product and was working fine.

Thanks,
