Razer huntsman mini "Tilde" (|)-button has been swapped with it's fn-button, "ESC". *help*

The last synapse download swapped the default mapping from tilde to escape. I depend on that button working as it used to, and there seems to be no way to switch it back on the synapse-app that I can find. This is the only button that has been swapped with its FN-counterpart. I can’t just re-map it back (I think?), as I can’t find a way to remap both the button, and a fn-modified version of the button. Any ideas? Have I pressed a shortcut and changed a setting? And is it theoretically possible with a work-around?
