I caused my problem, and now I'm hoping that someone can offer me a solution.

The CSS version reset
OLD uses 33Alerts-01.css?v=34 and index.css?v=34.
NEW uses 33Alerts-01.css?v=4 and index.css?v=4.
The css published version number reset from 34 to 4. This means browsers that cached the old CSS at version 34 will not download the new version 4, because 4 is a lower number, and browsers may ignore it. I believe that this is likely why the old version keeps appearing in the browser.

How do I solve this problem??
Thank you

There is no option to control the version. This is management internally, based on the number of times the page has been published.
This value is never reset automatically, it is increased by one each time you publish.
To increase the number, you can re-publish it.
