The problem with the left Shift(ω) and W (Watch_Dogs 2)

When holding down W and left Shift(a) it does not jump the obstacles, not break (press C, Space, etc do not work). When clamping other directions (ASD) and left Shift(a) all works. With the right Shift(ω) too, everything is OK, including when sandwiched W. If you turn the settings switch to sprint, not a deduction, all the rules, but odd to me not so easy)). What could be the problem?
