Bug on Users management with DT8.9

Hello,

WebSite: https://www.accueildegroupe.com
WP: 4.3.5 DT: 8.9

I would like to change a post (item of the listing) from the status Publish to the status Draft from the listing manager.
If I do that by using: Quick Edit, the post move from Publish to Draft: OK but the User is changed too from the original user (eg: Lambda) to the Admin User, and no way to move back the user of the post from Admin to Lambda.

By using Edit (instead of Quick Edit) everything is OK (no user change).

Is it possible to manually move a post from Admin to the old user ??? (I think it was possible withe the latest versions of Directorypress.
Thank you for your help.
Michel
