domain user permissions changed after update to 7.5.4 [not resolved]

Windows 2003 Enterprise Edition SP1
Plesk Reloaded 7.5.4 (updated from 7.5.2)

When viewing the permission of the domain user in "Web Directory Permissions" the permission to "Create files" is checked. This happend after updating from 7.5.2 to 7.5.4.

Im unable to change these permissions in "Web Directory Permissions".

Does anyone know how to change these permissions globally?

 

Can someone tell me, who is using plesk 7.5.4, what your settings are. And if you are able to change the permissions for the domain user.

Here are two screen shots. The first if my server running plesk 7.5.4 and the second is from the plesk demo site 7.5.2. You can see that the permission to create a file for domain user is selected. And its impossible to change that. Is this normal?
