I apologize you are not seeing the end month/year. When selecting the date range option there should be two blue squares showing the beginning date and end date.
What browser are you working in? Are you unable to select both dates in a different browser or even a private/incognito window? I have tested selecting these dates in your account and was unable to replicate this same experience. But we have seen some cases where an image advanced search based by "Date Range", has the end date's earliest date set to today's date. In these cases we suggest choosing an earlier start date first. This will allow you to choose an earlier end date as well. Does choosing an early start date first help allow you to select your end date?
