I may be on an island here but I find the following could be improved for clarity
I hope this doesn't seem too picky but here would be my suggestions:
Entry Criteria -> Re-entry criteria
Participant with the same unique criteria can enter after -> Participants with the same unique criteria can re-enter when in the following states
or
Participants with the same unique criteria can re-enter when they already exist with the following state(s)
A few times in support I've users people not quite understand the second option. For example, I've seen users choose every single status which can cause duplicates(even though they are different participants) to enter if they are still in an active status and get pulled into the participant source again.
