Whenever you adjust a package, the changes should affect all cPanel accounts using that package.
If a cPanel is not changing, you can expedite this process. Please follow these steps:
- Inside WHM, go to Account Functions, Upgrade/Downgrade an Account.
- Select the domain which will not change and click the Modify button.
- Leave the same package selected, and hit the Upgrade/Downgrade button.
- Check the results.
