Hi @kem104,
Thank you for posting in this community.
First of all, date in News web part is not the date when your news was created, but the time when your news was first published. As in the screenshot you shared with me in the previous question, the option is to show when it was first published.
Your case is by chance, because I tested and the first published date of the copied page should be the same. The first published date is an internal property of the page, so I got the first publish date for both news via PowerShell. You can see that in the 24Jun and 24AugCom, the first published date is same.
While I haven't been able to reproduce your problem, here are some things we can do to narrow down the cause of the problem.
1.Check the first published date of the news:
Start by installing the PnP module for SharePoint Online, and then run the following PowerShell command to see if there is an issue with first published date of the news.

#Connect to the site,please replace your site
Connect-PnPOnline -Url "https://yourtenant.sharepoint.com/sites/sitename" -Interactive
# Get the page,please replace your page
$pageUrl = "/sites/sitename/SitePages/pagename.aspx"
$page = Get-PnPFile -Url $pageUrl -AsListItem
# Get the first published date
$firstPublishedDate = $page["FirstPublishedDate"]
Write-Output "First Published Date: $firstPublishedDate"
If there is a problem with the date, you can make the following command to modify the date.
Connect-PnPOnline "https://tenant.sharepoint.com/sites/sitename" -Interactive
# Set your new publish date
$publishDate = '07/12/2014 00:00:00'
# Set the ID of the news item to update
#you can get edit site pages library's view and get the id from ID column
$newsItemId = 15
Set-PnPListItem -List 'SitePages' -Identity $newsItemId -Values @{'FirstPublishedDate' = $publishDate } -UpdateType SystemUpdate
2.Recreate the News Web part and see if the issue persists.
3.Try to use a different browser or your browser's InPrivate mode to see if the news occurs.
4.Check if the same issue occurs with other SharePoint sites.
5.Are other users facing the same problem? View through another computer or account.
