Hello, Henry0523!
Welcome to Apple Support Communities! From your post, it sounds like you're trying to delete certain apps on your Mac, but they are not uninstalling. We can help.
Since you tried using Launchpad to delete the apps, we recommend using Finder to delete the apps next. You can follow the steps for deleting through Finder in the support article below:
How to delete apps on your Mac - Apple Support
If the issue persists, try restarting your Mac next, then reply with the app names you're trying to delete if that doesn't help.
Best wishes!
