We are members like you, not miracle workers.
What part of the description is missing, only you know, and I can think of no reason why any part should not be there. List it and if necessary edit the description.
Telephone numbers, email addresses or addresses are not allowed, so if you are trying to put in that sort of information it will be removed.
You don't appear to have sold for a long time and there have been many changes inthe last year. Unless you are up to date that could prevent you listing. Apart from Managed Payments, the Classic Site has been phased out and you will have to use the Seller Hub.
