Left control and space do not work together

In single player and multiplayer if I hold left control (Sprint bind) I cannot use spacebar (Jump bind) if control was pressed first.
Ex: Holds w to walk, holds control to run, tries to use jump but doesn't work. Only w and control work, only sprinting.
Ex #2: Holds w to walk, holds spacebar to continuously jump, holds control to start running. Everything works fine, I'm now run jumping.
