departureTimeEstimated fields recently unpopulated

Hi there,

I’ve been pulling data from the departure_mon api for stopID 10115610. For the past few months departureTimeEstimated has come back populated but this is no longer the case since I pulled down more data last week. I thought it would be unlikely that all the busses for that stop had their Realtime data pulled, is anyone aware of any changes made for that stop recently?
Here’s the JSON I’m receiving back:
