[2020] Lock Input Method As Mouse Not Working

Trello link for the bug below. The update asked for videos of the issue. The lock input method as mouse setting does not work. I am on PC and I am using a Azeron keypad and a logitech mouse. I am from Spain so the option in the game menu is in Spanish.

With the "Lock Input Method As Mouse" set to on, the game still switches between mouse and controller input. Causes building/turbo build to not work and causes frame drops. Happens in all modes (creative and BR). In the attached clip I am holding the "place building" button (left click) and the turbo build option is on. As you can see, sometimes the builds are placed and sometimes they are not.
