I am trying to build what I thought would be a basic flow. I want to create a calendar event based off the "Date" columns (date picker) in a SharePoint List. I've read similar examples on this and other sites, but am apparently doing something wrong because I can not select the date fields for my Start and End times. My Flow looks like this:

As you can see, for "Subject", I have the option to select the "Start Date" and "End Date" fields. However, for the "Start time" and "End time", those options are not there. In the examples I've found (https://powerusers.microsoft.com/t5/Building-Flows/Create-calendar-event-based-on-SharePoint-List/td-p/300431) the Date fields seems to be there, as that user was able to enter them into their Flow. What am I doing wrong that is preventing me from selecting the Date fields?
