The app displays the preorder badge on the entire product if any variant is marked for preorder. This includes what’s shown on collection pages, home pages, and product grids.
At this time, it’s not possible to limit badges to only show when the selected variant is a preorder.
If you want to avoid this, you can:
Create a separate product listing for the preorder variant
Use custom messaging on the product page to clarify which options are available now vs. later
Let us know if you’d like help thinking through setup options that fit your store.
