Peak time period off by an hour

I feel like this is a recent development, but the peak time highlighting is off by an hour for my account. My best guess is that the DST switch for shifting them isn’t being taken being processed correctly because days during standard time are behaving correctly. And toggling the switch has not impact.

Thanks!

Do you have an example of the highlighting e.g. date/time, if there is an DST issue then it would affect the entire day’s record.
