# Inventory troubleshooting

> Problems you might hit with items and inventory, and how to fix them

Problems you might hit with your inventory, and how to fix them.

<AccordionGroup>
  <Accordion title="My items have become unlinked from their variant">
    **Why it happens.** Updating a variant by CSV in Shopify replaces the variant ID without telling Supercycle, so the items lose their link to it.

    **How to fix it.** Re-link the items from the Inventory table.

    <Steps>
      <Step title="Filter to unlinked items">
        On <Icon icon="shopify" iconType="solid" /> **[Inventory](https://admin.shopify.com/apps/supercycle/items)**, filter **Variant** to **Unlinked**.
      </Step>

      <Step title="Select the items">
        Tick the items you're re-linking.
      </Step>

      <Step title="Update the product">
        Select **Actions**, then **Update product**, and pick the new variant.
      </Step>
    </Steps>

    If items stay unlinked after the update, contact support from the app with the product handle and two or three affected serials.
  </Accordion>

  <Accordion title="An item can't be deleted">
    **Why it happens.** Supercycle blocks deletion while an item has cycles on record, so deleting it wouldn't lose that history. The message reads **Item #1042 can't be deleted because it has cycles. Retire the item instead.**

    **How to fix it.** [Retire the item](/documentation/manage/inventory/item-actions#retire-item) instead. That stops new cycles being booked on it and keeps everything that has already happened to it. A bulk delete does this for you: it removes the items with no cycles and skips the rest.
