A other problem

i set

"Event entry need to LOGIN

Only login user can be reservation event. (Not use email address)" to Yes.
and than i register a new event, is the "Additional Items" empty?
Empty only default value, because it is redundant when login user knows. Also, you can set same syntax additional items, if you need.
