The 1 point of lost EP is a known bug from when they ran some tests for the Kickstarterversary. All previously purchased EP packages before May 1st will be receiving a 10% boost to their EP for buying early when the Kickstarterversary rewards are applied. The rewards will be applied after Account Merging ends but before Domain Selection occurs and will be based on the total amount spent on pledge packages at that time. Unless you upgrade or merge another package, you should also receive an additional "Below $250 : 10% Store Credit" reward at that time.
