Hey Don,
You posted this thread over the weekend; our support hours are one reply within 24 hours during the work-week. So thank you for your patience here, and sorry for the wait.
When it comes to your issues with the ordering of events, we do have one known bug that affects the ordering of events within a given day, but I have not seen or heard of, and cannot recreate, the exact behavior you have here.
With this in mind, then, I would recommend doing the following steps:
• Deactivate ALL PLUGINS on your site except for literally only these two plugins: The Events Calendar and Events Calendar Pro
• Activate a default theme like Twenty Sixteen on your site.
When your site is in this state, take another look at the ordering of things. Do the same issues persist?
Let us know what you find!
Thank you,
George
