Mouse clicks have been flipped out of nowhere ( NOT SURE IF THIS IS THE RIGHT PLACE TO POST IT)

Hello, I've recently came across this problem where my mouse click have flipped randomly. For some reason i can't seem to switch it back to normal through the in-game settings. I've rebooted my laptop see if the problem was coming from it but it didn't help. I also tried hextech repair tool but that didn't work either.

I also play with my mousepad ( If that helps you guys in any way )

Thank you so much in Advance for your time and answers!
