Throttles work incorrectly..

[rstwx]

Hi! At the moment, I have this problem:
I don't have any throttles in real life, and I use the F1, F2, F3 keys.
For example, on the A320NEO FBW, when using the F3 key, I slowly increase the thrust of the engines and can easily increase it a little for taxi.
But when I try to do this on the A350, the thrust immediately switches to Climb mode, and only then it can be slowly increased to Flex or TO/GA.
Also, when landing the aircraft, after turning on the reverse, I cannot move the throttles to the Idle position by pressing the F1 key, instead the throttles are moved to half reverse.
How can I fix it?
All the binds are set, the throttle regulation was also correct.
