After deleting PM, Appian is picking previous versions

Hi All,

Currently, we are using the 23.2 version. I have deleted the process model's latest version, and I realized the earlier version will not be enabled or activated automatically. I saved the earlier version of that process model and then published it successfully (Version No. 10). Now, I am facing some issues. Whenever the above process model is referred to, Appian doesn't always pick the latest published version, sometimes picking an earlier version (Version No. 9).

Can anyone advise on the below?

How do I make sure Appian picks the last published version (version #10)? by restarting the application server?

Appian is giving provision to delete the version, but is it recommended to delete the older versions?

If yes, then how do I make sure the earlier version is active?

Thanks in advance.
