Pages opening in random country locations from Google

[davidfoster1983]

A really random one, I noticed today that my collections pages are opening in different country versions from Google and I cannot see for the life of me why this would be. 

My store is set as UK default with country/region redirections for /de, /fr and /es, but I am finding some pages open in each of these when I access them via Google SERP (I am UK based). 

Any suggestions on why this might be, and possible fixes would be greatly appreciated.
