It's due to your setting for the option "Force canonical URLs on listings" in the HikaShop configuration. See the documentation to learn what the different settings of this option do:

There are also quite many more threads here in the forum on "canonical URL", including how to delete wrong ones per mass action. For finding out more you may use the search function here... just make sure the spelling is correct
