It's just far too common a problem with that kit. It's just not fair to be marketing and selling a radio that is so prone to issues and is far too picky on what it wants to work with. You certainly shouldn't have to buy all sorts of glitch busters and specific esc this and servo that to make it compatible.
All I am doing is giving my 25years plus experience of this stuff and recommending that the OP returns what is obviously a defective bit of kit and replace it with something that is known and proven not to have any issues. By the way I don't appreciate the bash because it isn't personal - far too many people (not only on here) voice their opinion of this kit in not a very favorable light.
Your Radio is the number one most important bit of kit you have and if you can't get any confidence in it due to glitches or whatever it's doing then you won't enjoy your racing through constant worry the thing is going to end up in the wall through no fault of your own.
