What this means
This change would leave an already published GTIN with nowhere for plain scans to go, so the whole transaction was rolled back — including the edit that triggered it.
Why it usually happens
Deleting or re-typing the link that currently holds the GTIN's default slot.
What to do
Put another link in the slot first, then make the change. Deactivating the current default is allowed and is the softer move: the slot stays filled, and the resolver still has an answer for a scan.
