The record of the default row is then displayed, so just edit it:
Do not forget to save.
Priority of default values
Be careful, some columns can also have default values (current date, user ID), and these take precedence over the default values of the table or the view.
Note that the default values of a table apply to all views that do not have default values. In other words, if they exist, the view's defaults override the table's defaults.
To clear the defaults, open them and then delete the record via the icon at the top right.
