No Change Required
In this report, my Column Header is using a Spreadsheet Layout, but the elements inside it are not respecting it.
As you can see, they were moved freely. Even if I select "Arrange In Container/Spreadsheet Layout" they keep their current positions and doesn't realign.
If I remove the Detail band and select "Arrange In Container/Spreadsheet Layout" in Column Header, they are repositioned as expected.
The same behavior is happening for any band before Detail band.
Also, if I change the layout of the Detail band to any layout and after that I change the layout of the Column Header to Spreadsheet Layout, it changes the Detail band layout also to the same layout as Column Header.
JRXML file is attached.
