I came across a weird problem when i was trying to replace the CampaignMember status picklist with 2 new values(Invited/Attended). I deleted Sent/Responded values.
It worked fine on the existing Campaign records. But when i created a New Campaign record and tried adding new CampaignMembers to the Campaign, i see only Sent/Responded and not the newly added ones. In the object field definition i see that the Sent/Responded are back. How do i fix this or workaround this problem? I only want Invited/Attended.
