Access List with Mac

Hi everyone. I’m trying to control which AP a client should connect to by MAC address.
These are the configurations:

Ap1:

/interface wireless access-list
add allow-signal-out-of-range=3s authentication=no forwarding=no mac-address=\
    10:96:93:44:6B:** signal-range=-120..-74
add signal-range=-90..120
add authentication=no forwarding=no

Ap2:

/interface wireless access-list
add allow-signal-out-of-range=3s mac-address=10:96:93:44:6B:96 signal-range=\
    -75..120
add allow-signal-out-of-range=3s authentication=no forwarding=no mac-address=\
    10:96:93:44:6B:** signal-range=-120..-76
add signal-range=-90..120
add authentication=no forwarding=no

I also added another rule for all other devices.

the client is now connected to AP1 with a signal of -77 and is currently close to AP2 (the signal should be better than -75)

what am I doing wrong?
