"As Timeline" Visualization

I would love for this specific page to always look like the first screenshot, where it is sorted chronologically. When I first enter the data, it is sorted this way; however, when I click off to another page and then come back to the timeline page, it looks like the bottom screenshot, where it is sorted alphabetically. I am able to click on the x axis twice in order for it to return to its original first screenshot, but it would be much better if I could simply open the sheet and have it look like the first screenshot every time.
