In this article we show with an example how to delete data in the app. The way to do it will be the same for the rest of the registrations you need to delete in the program.
When you want to delete and existing registration you will go to the table where the registration you want to edit is saved. In this example we are deleting an entry registration. So we go to "Actions" and select "Entry" to see all the entries. Once we are there we click in the row we want to delete and it will automatically become editable.
Now an icon with a trash can is shown at the beginning (left side) of the row. To delete that row/registration we just need to click on the trash can icon. 
When you click, a pop up message will appear asking if you want to delete that record. If you click "Yes" the record will be deleted and you won't be able to recover it and if you click "Cancel" the delete process will stop and the data will stay in the app.
