Blogger vs WordPress Blog

Hello there! My blog post 'Spikes' was published on Sept. 22nd; however, the post before it called 'Flow' was published on September 6th. Unfortunately, Flow is showing that it was published on the 22nd, after Spikes. They both show on the site that they were published on the 22nd. How can I change the order back to its normal order, with Flow on the 6th and Spikes on the 22nd? I have no idea how it got rearranged in the first place. I think I did something on the APP version of wordpress but have no idea what.

Thank you!

The blog I need help with is memoryboxmom.wordpress.com.
