Mixed computers

[Gaelds]

Hello, I use veyon 4.8.3 with LDAP Basic and windows AD computer groups. But in several new rooms (Win11 23h2), computers thumbnails are completely mixed up with other rooms computers...
Here in "T100" room, I see the right names of 29 computers in T100, but the thumbnails are displaying other random computers from other AD groups. Some of the computers that are displayed are not even joined to the windows domain.

For example, instead of T100-0821-P04 thumbnail, I see computer "M209-0617-PROF" thumbnail. And By clicking on thumbnail, i get control of "M209-0617-PROF".
T100-0821-P04 MAC addresses : d0:8e:79:07:6d:a8 and 0a:00:27:00:00:0a (virtualbox)
M209-0617-PROF MAC address : 48:4d:7e:c6:1d:7e

M209-0617-PROF and T100-0821-P04 are not in the same computer group or OU.

Same problem when i use LDAP Pro Add-on and Organizational Units instead of groups:

thanks for your help!
