X now allows the fragment or the # part of the URL to be added when clicking a jump link. That is the default behavior of the browser and is good for UX because you can share a specific part of your page.
If you want to change the hash (#) part, you will need to change the ID of the Content Band since I see you're using Visual Composer. I don't see the ID field now though. It should be above the class.
Regretfully, you will need to use the generated ID for now. I'll post this in our issue tracker so our development team would be made aware of this problem in due time.
By the way, if your content spans Fullwidth again, go to WPBakery Page Builder Settings > General and make sure "Legacy X Integration" is enabled. A common request we get is to not overwrite parts of the WPBakery Page Builder. For more details regarding the changes, please check out our latest release notes at https://theme.co/apex/forum/t/release-notes-pro-2-3-x-6-3-cornerstone-3-3/44607
We're sorry for the inconvenience.
