Two dots in Amazon URL make products unreachable

There is a strange issue with my WooCommerce affiliate website wherein the product links are not reaching Amazon correctly.

When I click the “Learn More” link that is supposed to take me to the product on Amazon, it takes me to Amazon..com/xxx”.

As you can see, there are randomly two dots after Amazon, looks like a script has gone wrong or something. This makes the link unreachable until the extra dot is removed.

Is there any solution to this?

Thank you in advance!
