session end times now wrong

As of a few hours ago, in the downloaded sessions the start times are correct but the end times and durations are totally wrong (I think it's mainly the "asleep" times that are way too long now). See attached download versus Snoo log in app for same time period. Sessions should be approximately 21:52-2:16, 2:41-5:03, 5:03-5:16, 5:34-8:14, as in image

At second look, actually this is a problem with when the code for exporting the data (> data_sessions = client.export_sessions(start_date,end_date)) is run multiple times within a single Colab runtime sessions, for some reason it keeps adding to durations. Runtime must be restarted to get correct values
