Xfinity streaming app, viewing tv shows available by "Days of the week".

I've used the Xfinity Streaming app for a few years to view which tv shows are available to view based on the day of the week the episodes were aired.  I just noticed one of the shows I watch, The Amazing Race, has been showing new episodes for the past two months but the show is not listed under the "Days of the week" section for Wednesday, the day the new episodes air.  Does anyone know if Xfinity limits what shows are listed in the browse by "Days of the week" section?  I have also noticed the home page section for the prior day's shows will intermittently disappear from the home page and then reappear the following day.
