The Flash and Superman & Lois keep changing places

So to give an example..

The Flash S07E03 was before Superman & Lois S01E04, now it's appearing after it, even though The Flash airs beforehand.

This happens potentially with all episodes that aired on the same day at least from November 2019 onwards, just update the site again and again and watch them jumping around. I could not reproduce this for earlier dates. I guess using only the date for sorting is not sufficient. @SaiyanOfDarkness Is there any valid source for the air"time" in addition to the date of each episode?

Or we can sort by name as well.

What about this - https://en.wikipedia.org/wiki/2020%E2%80%9321_United_States_network_television_schedule?oldformat=true?

Indeed, that helps a lot, at least me. Thank you so much :)
