Inverse trigonometric functions work in Facer Creator, but not on the watch

If I add a Text element, and use the rocket to set the Text to (atan(1)), it shows 0.7853981633974483 in Facer Creator. However on my watch it shows 0. I also added a Second Hand and set the rotation to (atan(1)*100). In the Creator the hand moves to the right. On the watch, it points straight up, so it must be reading 0. Same problems occur with asin and acos.

My watch is the Asus Zenwatch 3. Running Facer version 3.0.3.

@facerstaff Could you please investigate this?

@facerstaff Any ETA on a fix for this bug? It makes atan, acos, and asin completely unusable.
