@HH1 Thank you so much for this information! It is greatly appreciated. I have passed on this information to the appropriate team for you. Additionally, they are requesting a screen recording of you attempting to change the time to AM and not PM, and it reverting back to PM/not sticking to AM. If you could gather this and reply in this forum with that video, this would help benefit my team. If not, no worries, the screenshots and information you have provided is good enough! 
I will make sure to update you accordingly once I get more information back from them on this concern. It may take some time, so I appreciate your patience in the meantime. If you ever need in real time updates, you can also reach out to our support team here.
