[Tasker Tips & Tricks] darkpixie:
I have scene with all buttons for calculator and also TextEdit and Text1 to show calculations, but only numbers show, the plus and minus signs are not showing, thus the code is not working correctly, but since I double checked it inside 4u1 and 4u3 versions, I assume its a bug,

below the XML file:
