Original Composite Plugin is not working

We have had the composite plugin running without issues for 2 years, but now products are not displaying properly anymore.

When i checked on woo, i noticed it renewal fee was due so I paid that however the products are still not showing as they should.

I have tried deactivating and re-activating the plugin, I have tried modifying and re-saving the composite product, I have sent a message to support via woo but have not received a response.

These are all composite products, and none of them are displaying as they should anymore:

Help, please.

Thanks
