5 finger swipe left is set to Ctrl + tab to move previous tab. It works as expected moving to the previous tab, Five finger swipe right is set to control + shift + tab to move next tab and instead of moving it brings up a box with all the available tabs behaving differently. I've tried command + option + right arrow and it behaves the same way.
