Radios missing on mac

i’ve bought a licence for AS
when i use it on my macbook pro 16" late update,
i see only 20 radios of high quality , but when i use it on an Asus under windows 10 late update, i see 65 radios of high quality.
Why this big difference ?
On another hand, if i dont use AS during sometime ( let’s say 1 hour), then no radios cant be seen anymore .
why this phenomena ?
Am i the only one to meet these bugs ?
Have i missed something or will an update fix them ?
Thank you… and hoping to have been understood in spite of my scholar english !
