Why was my bundle or bundle content deleted automatically?

Note: You may receive an “Action Required – Product Variant Deletion” email if a variant is edited in your original product or in the bundle parent product (in Shopify or the app). This means the affected bundle has been deleted, and the alert is to help you review and update your setup.

If you notice that a bundle has been deleted from the Simple Bundles app, try to locate it from the product variant page in Shopify using the app extension. If you see an error with "No bundle found," then the bundle was mostly likely deleted in Shopify as well.

When the actual product variant used to build the bundle no longer exists in Shopify, the app will also remove that variant. This can happen if you:

Change a product from a one-to-one variant (Default title) to one-to-many variants.
Bulk update product variants in Shopify via CSV upload, which can sometimes delete the bundle variant entirely.

Shopify mentions this behavior in their help doc: Importing products with CSV. https://help.shopify.com/en/manual/products/import-export/import-products

Variant IDs change when option values are updated

Here’s a useful list to prevent bundle deletions in the future:

Avoid changing variant option values in Shopify
Changing Option1, Option2, or Option3 values creates new variant IDs and deletes the old ones, breaking the bundle connection in Simple Bundles.
Be careful with bulk edits or CSV imports
Changing option values or switching from one-to-one to one-to-many variants can delete variant IDs. Always confirm that IDs remain the same after bulk changes.
Update bundles before archiving components
Add the new product (active) to Shopify and update the bundle before drafting or deleting old components.
Check for nested bundles
If a product is in multiple bundles, changes to it can affect all parent bundles—review dependencies before editing.

Back up your bundles

We recommend backing up your bundles by exporting them once you’ve completed building them: Bulk export bundle data. This gives you a restore point if variants are accidentally deleted.
