When we mix different types of element... in some cases (it seems random), we are no longer able to move SOME elements (not all of them) up and down by using CTRL-Up or CTRL-DOWN or by using the menu option "Move up" or "Move down" on the element.
In addition, the option 'Content / Reset Sort Order" does not sort these elements.
Any idea how to resolve this?
Thank you in advance,
Alain
