When Purchassing minecraft java it takes you to micrsoft store

I personally have not experienced this; my friends have. While they were purchasing Minecraft they clicked on "Buy Minecraft Java" and it took them to the microsoft store to download windows 10 edition. Not knowing what they were about to do they clicked the purchase minecraft button, and bought the wrong version. This is obviously a problem and I believe this should be fixed asap because this is wasting money by buying something they never wanted in the first place.
