Bookings personal page shows incorrect times, not my "regular working hours" from settings

Hello I'm also having the same issues as described here - MS Booking is not adhering to the "regular meeting hours" as defined in Outlook Online. 

The only way I've been able to make this work is by selecting the "use custom availability hours" particular service booking itself.  It appears that this has been a long-running inissue with no response from Microsoft. 

I am a huge fan of Microsoft products and solutions but this isn't right.  It would be better for Microsoft to remove the option than provide us with option and settings which simply don't work.  Maybe I'm missing something - if so please let me know and thanks!
