Offer message details being flagged as contact details

[jimrya3]

I've sent an offer to a customer who wanted 2 of my listings to be sent as one. Rather than create a new listing, the following information was provided:
---------------------------------------
This price is to include Formula One 2001, 2002, 2004-2006 (5 games).

The other two games, Formula One 2001 + 2002 are listed as eBay item number ********* (redacted for customer privacy)
Also included is the postage (Royal Mail 1st class International economy).

To be sent to a US address to be specified by the customer.
---------------------------------------
I received the following error message: 

• We've noticed that your offer included some contact information. We don't allow email addresses, phone numbers or URLs in offer communications.
  
  

I've tried taking out the item number but the message still remains. Does it think that the years are phone numbers? Also tried with 01 but to no avail. 

Any help would be greatly appreciated.

SOLVED:

The following offer message was accepted by eBay's filter:

Also to include eBay item number *********** . 5 games in total

International economy postage included

It can only be the 'brackets/Formula One or US address' was flagged. Either that or a temporary system issue.
