Repeating multiple days in a week

When I want to repeat a task on multiple days during the week (say Mon, Wed, Fri),  I;ve gone in and set up repeat weekly, then choose the specific days of the week for it to repeat on.  However, after I've saved and look at my calendar schedule, the only day it shows up on is one of the days.  If I go back into the task to edit, the weekly repeat screen only shows one of the M/W/F days as being checked.   It doesn't appear that it's saving all of the days that iv'e previously checked to repeat weekly.  I'm using the google Chrome browser Version 65.0.3325.162 (Official Build) (64-bit)  and am currently in my trial period with Week Plan
