For this one, request a call from Amazon SC and ask them to walk you through the issue.
If you need to reduce the title for the Character limits for the kitchen category, have a reduced title ready so you can update with SC on the phone.
Your aim is to:
speak to the Amazon SC catalog team
ask them to review the issue and tell you how to fix it
and for them to WAIT on the phone with you and walk you through step- by step, how to change your title. You don’t want them to leave the call until the title has been accepted and there is no system error.
Here is how you request a call:
*** ignore the yellow box under #1 which details ‘category’, yours is the one above ‘fixing a product page’, but you won’t select that either because it won’t put you through to an agent – Choose the investigate other option
