TYPO3 Core

When I save a form with the form BE module, the order of defined options of a single-select field gets sorted in ascending order instead of my manually selected order when I change the form, save it and then re-open it in the BE Form module editor.

Every time I re-open the form in the editor, I have to re-arrange the options again.

Oder before saving the form:

Label Value
5 5
4 4
3 3
2 2
1 1

Order after saving the form:
1 1
2 2
3 3
4 4
5 5
