@d-healey finally solved the problem by ticking the "show text box" i dont know why but it worked

@ToharShefiRafeld Also if im adding this line

const var Knob1 = Content.getComponent("Knob1") .set("numStrips" , "72");```

its signals that the numStrips is "overwritten by script"
but still the same problem

@d-healey Thanks for the quick answer, yes the image is in the folder, but im using the the property editor not working with the code editor

While assigning a filmstrip for a knob i have this problem:

when i set the right amount of frames everything works perfectly but if I switch page and come back to the interface designer it stop working, assigning the number of frames "solves " the problem for a minute and it stops again. Also exporting without the rotation.

Maybe do you have a solution?
