PS/2 touchpad buttons are both recognized as a right click in tracker

On laptop (an IdeaPad 100-15IBY) the touchpad is detected as a PS/2 touchpad and works fine except for the mouse buttons that seem to be both mapped to the secondary mouse click in Tracker, as clicking on the desktop always opens a context menu. in WebPositive, the mouse seems to work just fine, right-clicking opens the context menu and left-clicking also does what it's supposed to do. And the About screen also detects the right and left click, as I can only move the replicant with the left button. Expected behaviour would be that tracker does not open the context menu on a left click.

EDIT: The context menu is only opened on the desktop itself. In a normal tracker window, everything works as expected
