How to stop Libreoffice Base from auto creating new empty records

Hi there. I’m using Libreoffice Base to administrate MySQL database through JDBC.
When I get to the end of a table, it tries to auto create a new empty record, and since there are date fields, JDBC returns an error message that date could not be null. This is some kind of chain reaction, leading to endless error messages and crashing the whole program.
Is there a way to disable automatic creating of a new record? I’d like to just edit the existing lines without autocreating new ones.

It only does this if you click on the row that has what vaguely looks like a star in it. This is normal behaviour. Navigating to the end of your table means clicking on the last record, not on the empty row beneath it.
