sort_order=”desc” not working

Dear plugin author, I hope you are OK and webvital ?? enough to find a solution for this.
I absolutely love your plugin. Hope it will be continued.
Nowadays I suffer a problem: as said in the title sort_order=”desc” won’t work anymore.
I set a page-order for each page – this is not ignored, but the list does not sort the other way round.

Thanks a lot.
