Problems with radio channels

Hello. When connecting the Taranis remote control with the TBS module, the channel 7 level in Mission planer becomes 2000 and does not respond to the switch on the remote. When the remote control is turned off, channel 7 drops to the level of 1020, and the throttle level becomes 1134. This was not always the case, I made several flights on a quadrocopter and then noticed this oddity.
