[Authoring MP] MPBPA analysis tool always report "Alerts should have name and description defined"

This is related to the alert configuration. You must verify that

• when you open a rule, switch to configuration and check what is missing in the alert section.
• If it's not there, check display name and description for the alert.

If you have separated out your strings into a language pack instead of putting the english strings into the base MP, then you will have to live with this error.
A best practice should be to have a base MP contains only the ENU strings.
