Rejected release dates

Hello. I've recently tried to add some release dates for the film "Scenes from the Class Struggle in Portugal" by Robert Kramer and Philip J. Spinelli, but most of them were rejected (the reference is the following: 260422-192700-116000)

Were they rejected because they referred to the same venue? If so, why were the oldest dates rejected while the most recent one approved? Shouldn't it have been the other way around?
