After recently updating our site to v4.3.6 i have noticed that when using the 'search products' feature to search the site the results displayed sometimes have option combinations tagged on the end of the product URL rather than just displaying the standard product URL - this means that search results often display a less popular option rather than the one set as default position 1.
This is a URL displayed after a 'search products' :
This is the URL displayed for the same product when found using product filters etc:
This only seems to affect products created since the update, products that were created before the update don't seem to behave like this, also when you use product filters the results are displayed as you would expect (with the option set in first position being the one that is displayed).
Thanks in advance
