I have ran into similar issues, bought 4 cases of command switches just before COVID hit at a show from a reputable dealer. Almost half had malfunction issues all needed the” derailing fix” done to them , one had a broken tab on the rail that makes contact on the actuator, and my last one has a jitterbug issue where it throws out without a issue but when comming back to keep it from derailing it starts to dance and makes a striping noise. Customer service as of late has been bad on hold no voice mail no email response. It’s a shame issues like and others happen. The hobby is expensive and I get that, you know this go into it but at least the products functionality should be the least of your problems.
I feel your pain
