After I change the admin password I cannot login with that password

MaartenB

on a xs1920. 
When I change the password (Webbased) to for example: 78901 as soon as I hit apply it chucks me out and I cannot login with that new password, also not with 1234. So I have to reset the device again. I tried different passwords, no luck.
What can I do?

Encoutnerted the same problem before, it's looks like the browser has keep the old password once use the private browsing mode then can access with the new password.
