Just Enrolled

Hi< can anyone help with programming a Galaxy 520.

I've installed 18 Max 4 readers and got 19 groups, each reader is outside a room with door contct and a detector.

Once a tag assinged to the group is prsented to the reader the door will open and presented tafg for 5 seconds the room will set. Ive also got around 40 users some having access to 5 readers (Rooms) the others having access to 2readers ect..

Example user 17 (security) has access to A2, A3, A6, B2, B3, B4, C2

I've programmed the user with the above groups.(max reader No

Another example user 54 (book shop) has access to A5, B2.(max reader No

When I present user 54 to security room door it also opend that door, which is not wright. I've enabled D8 as a common group below the group restrict and also enabled it.

I can see why the door is openeing because of D8 assiged.

Can someone explaine to be what i'm doing wrong please
