We are using Sitecore 9.1 with JSS and have a fully functional site running using Angular -- all working great. Now, we would like to add personalization to our site. To do so as a simple starting point, I navigate to our application and insert a new page to our "home" root. I add a simple Left Navigation component to the page and then go to Personalize the display. I add a rule to "Show" the component when the day of the week is Monday and default to "Hide" the component otherwise like so: 
As soon as I get back to the Experience Editor and choose the "Change condition" dropdown and pick the "Check Day of week" condition, the component does not hide. (it is not Monday) Odd thing is, sometimes this works for me but when I save the component, it reverts to no longer working. (not hiding the component when I choose the day condition)
Any ideas why I cannot get personalization to "stick"?
