but I can't seem to delete the application. Please help!
Hello! @hall.christine.f
Welcome to the LastPass Community.
We truly apologize for the problem; in case you can see two extensions in your Safari browser, please remove all extensions from the browsers and also from your applications in your finder, once done please access your app store and download the app again.
Please let me know if you need additional help.
Greetings!
