ChimePro 2 connection to Orbi Satellite

I installed a ChimePro 2 to improve the Wifi connection with my Video Doorbell 2. Unfortunately instead of connecting to the Orbi Satellite (RBS750) which is less than 4 meters away, it always connect to the Orbi Router (RBR750) located 10 meters away on the floor above, leading to less than RSSI -70 signal strength. It also sometimes switches to 2.4 GHz which improves the signal, but most of time stays on 5 GHz. All my other devices (including Ring Spotlight Cams) always connect to the nearest Orbi Satellite, thus I wonder about the specific behavior of the ChimePro 2 when it comes to selecting the best Wifi signal coming from the nearest access point.
