When Blocked Dates have the exact same title. it is causing some sort of calendar glitch to only show the first instance. meaning if you have two blocked dates for "Floor Refinishing" one in a range from 8/1 to 8/7 at one space, and a 2nd blocked date for "Floor Finishing" in a range from 8/5 to 8/10, on those days that cross over, the blocked date gets combined, rather than show two instances.
If you adjust the name of the blocked date to be slightly different, it appears to show, but I would prefer to leave my blocked dates the same.
