Problem using grouping and multi-value

[MarkRom]

I'm not sure why when using the grouping and multi-value option the saved values ​​are duplicated. Without the grouping option the values ​​are saved correctly without duplicating.

Apex version: Oracle: 12c - Apex 20.1

The code I am using is like the example:

SELECT e.ename d , e.empno r , d.dname grp FROM emp e LEFT JOIN dept d ON d.deptno = e.deptno ORDER BY grp, d

With Grouping:

Without #Grouping

Properties (All other values in Defaults):

Can you create the same behaviour on apex.oracle.com?
If so, can you grant me access to your workspace on apex.oracle.com? That way I can take a look at this specific problem.

Thanks for the demo workspace.

There seems to be a problem with the 'Drag and Drop Sorting' setting in combination with option grouping. If you disable 'Drag and Drop Sorting', the item will work just fine.

I'm not sure what the cause of this bug is, but is it possible for you to disable the 'Drag and Drop Sorting' setting in your case.
