Another extend table issue

[Sarah Bouil]

Table A -> 2 Fields Table A5 and Table A1 etc

Table B-> 2 Fields Table B1 and Table B2

   Table B1 field is referencing to Table A

Table B is extended from Table A

So if I create a record in Table B, the empty record is creating in Table A, the empty record should not create in Table A when I create Table B record right 

Screenshot is below

please help me on this

Table B fields:

Since Table B extends Table A, Table B inherits the fields from table A. If you only fill in the fields for Table B when creating a new record there, then the record in the parent Table A will have empty fields. This is expected. What is your problem?
