Links (often) direct to wrong Amazon stores

Hi, I have some issues in that many of my visitors are being directed to the wrong Amazon country stores. For example: U.S., German, and Canadian visitors are often directed to Amazon UK, UK visitors to Amazon DE, etc.

I am located in the U.K. and when I test my Amazon.com links they redirect correctly, although it takes a few seconds loading time.

Still, I see that the plugin is currently not working properly 80% of the time on my site.

Not sure what the issue is. I am using Quick Cache but have tried to disable it and it didn’t improve the situation?

Any feedback/ideas would be appreciated. Thanks.
