Files and Applications are misslocated in Finder after update Monterey 12.3

I just updated to macOS Monterey 12.3. After the update, everything looks fine. But when I clicked on Finder > Applications, all of my previously installed apps are located in Macintosh HD.

Here is what shown in Applications folder. Basic system applications. Located in Macintosh HD - Data

and

here is what shown in Applications folder located in Macintosh HD

when I clicked the application in the Macintosh HD's folder, it execute an installation. Like a fresh new app installation.

Why is this happening and how can I solve this?
