app just creates its own rows and columns in the database ignoring mine - MIT App inventor and firebase

I am making a project for university is basically an warehouse app that sells medicine to pharmacy stores problem is i am using Mit App inventor2 with firebase for database and it just fails i have made some rows and columns and every time the app is trying to get anything from database it creates its own column with rows ignoring mine

This is the database and the EPharmacy is the problem that's the name of the app and it is also the column it creates by itself

A block of code to login in the app

Has your issue been resolved, now you can login correctly ?
