RSSI problem with ESP8266

Hello,
Since I installed the ESP8266 module, I have a problem on QGC.
How to fix this problem?
See the video:

Personne pour m’aider? Comment choisir une seul ou plusieurs source RSSI?

How do I deactivate the RSSI of my Graupner radio and display only that of my ESP8266 telemetry?
I tried the following settings:
RSSI_TYPE: 3. (because I am in SUMD Graupner mode)
RSSI_ANA_PIN: 103
RSSI_CHANNEL: 8. (because my RX servo plug is on the CH8).
RC_OPTIONS: 0
I tried that and it doesn’t change anything

Please help me, how do I deactivate the RSSI of my Graupner radio and only display the ESP8266 telemetry RSSI? And nothing else.
