Code Signing issue

I purchased a Comodo Code Signing Certificate, and when I select that in my Metro app, and build, I get

Error4 File content does not conform to specified schema. The 'Publisher' attribute is invalid - The value 'CN=Falafel Software Inc, O=Falafel Software Inc, STREET="512 Capitola Ave,", L=Capitola, S=CA, PostalCode=95010, C=US' is invalid according to its datatype 'http://schemas.microsoft.com/appx/2010/manifest:ST_Publisher' - The Pattern constraint failed.C:\Users\jwaters\documents\visual studio 11\Projects\App1\App1\bin\Debug\AppxManifest.xml1057 App1

I found this more detailed message

'CN=Falafel Software Inc, O=Falafel Software Inc, STREET="512 Capitola Ave,", L=Capitola, S=CA, PostalCode=95010, C=US' violates pattern constraint of '(CN|L|O|OU|E|C|S|STREET|T|G|I|SN|DC|SERIALNUMBER|(OID\.(0|[1-9][0-9]*)(\.(0|[1-9][0-9]*))+))=(([^,+="<>#;])+|".*")(, ((CN|L|O|OU|E|C|S|STREET|T|G|I|SN|DC|SERIALNUMBER|(OID\.(0|[1-9][0-9]*)(\.(0|[1-9][0-9]*))+))=(([^,+="<>#;])+|".*")))*'. The attribute 'Publisher' with value 'CN=Falafel Software Inc, O=Falafel Software Inc, STREET="512 Capitola Ave,", L=Capitola, S=CA, PostalCode=95010, C=US' failed to parse. 

It looks like the regexp doesn't understand PostalCode, which is in my certificate's Subject.

Is there any way to get around this?
