Hi everyone

i have an issue with something in the Database,  i defined a datatype  which include two other fields which are two other datatypes  and they are both also defined as an array .

now if i look in the db after inserting data in , i can see in my  first one the ids of my foreign key  of creditrequest , but in the other table there is null 

where can i see what is wrong here ?
