Why Is Shopify Changing My Product Category?

[Kathy_Bankston]

Regarding this: 

->Product organization

-->Category

--->RINGS (my input- which shopify changes to JEWELRY after a few days)

----->Determines US  tax rates

If I input RINGS - a few days later I come back and Shopify has changed it to JEWELRY.  Why is Shopify doing this and how can I prevent it from doing it?

Just a wild guess but it could be changing based off of the UPC you have entered for those products.  Again, big guess but if 99% of the stores using that UPC code assign that item as jewelry, then it might automatically populate to that category assuming that is the most correct one.

Handmade - no UPC So I don't think that is it.

Odd.  Ours has changed in the past as well and we thought it was because of the UPC.
