HI;
i have two department's in the department table of my database. a department contains a list of velden. but on the second department the list with velden has first all null values and then the values that i need. it looks like the list of velden is not reset after the getting the first list of velden. this is an image of the variables
i think it's a mapping issue but i cant find the solution.
this is the mapping of departments
