Emulator for Bangle.js2 is loading Bangle.js1 file

When opening blackjack in the emulator and selecting "Bangle.js 2" as emulation target the script for Bangle.js1 is loaded. Obvious by the some visible parts missing (smaller resolution of the 2) and the error message:

Uncaught ReferenceError: "BTN4" is not defined
at line 1 col 17
setWatch(hitMe, BTN4, {repeat:true, edge:"falling"});

Uncaught ReferenceError: "BTN5" is not defined
at line 1 col 17
setWatch(stand, BTN5, {repeat:true, edge:"falling"});
