L button not registering clicks

Recently I used WD-40 electronic cleaner as my joycon was stiffening up during gameplay which i’ve successfully fixed before using it, but I think that it may have damaged my L shoulder button? I believe excess has trickled down into the shoulder piece. Originally after I suspected it got into the console, my ZL button wasn’t working after with registering clicks and difficulty pressing the button. I left it alone overnight to dry and now my ZL button functions like it used to but now my L shoulder button clicks perfectly, but none of the clicks register.

Could something have shifted inside that the console would need to be opened up for? Or have I potentially damaged it and need it fixed. Also, not so much a tech pro so please dumb down explanations for me lol.

Thanks.
