Product Combinations Repeating And Not Showing All


I have recently upgraded from 2.2.4 to 4.3.2 and happy with the way it is progressing even with a few niggly problems.

One problem I need to fix quickly is with product combinations in the Admin section. When trying to edit the product combinations in the backend and there is more than one page to be displayed, I see the same combinations displayed on every page. No matter what page number I am on. However they do appear in different a order.

I have upgraded to 4.3.3.SP1 and it looks to work correctly on my dev machine but when I put it onto my production machine the problem still is there. I have cleared the cache both through the admin page as well as physically deleting everything in var/cache folder.

Not sure what else to look for / do. Any ideas ?
