Left Joycon Rail Issues

I’ve started noticing an issue with my left joycon rail where, occasionally, it starts reading phantom inputs to the right on the analog stick. It’s not joycon drift, I’ve had no issues using my joycon on other consoles or in wireless mode, and all of my joycon experience this behavior when docked to the console. I have a Japanese model Switch. Has anyone else heard of this? Would I have to replace my joycon rail?

Try calibrating it docked in the rail I had this problem a while back if calibrating it doesn’t work check for dust and corrosion in the joycon and rail if there isn’t that get another joy con and try that leave replacing the rail until last isolate everything else first
