let dbURL = 'mongodb://127.0.0.1:27017/Loc8r';

This is shown in my Terminal (Visual Code)

So it seems i have a connection with my local MongoDB database Loc8r

This is shown my browser: 2 locations

But if i open MongoDB Compass, and use this connection string: mongodb://localhost:27017
Then Go to Loc8r and select locations > in my local mongoDB / Loc8r , 3 locations are shown

My Question: why do not all 3 locations show in my application/webbrowser?
