SimpleButton alpha problem in HTML5

Hello, I have a problem with SimpleButton transparency when exporting to HTML5

the button was created in Adobe Animate CC and exported to actionscript with a class name.

when imported as swf in OpenFL, if I try to set alpha property to a value less than 1 and bigger than 0 it will still be opaque.

only alpha = 0 works which makes the button invisible.

I even added the button to another movieclip and write:
mc_1.alpha = 0.5;

the movieclip mc_1 looks transaprent correctly except the button is insisting to look full opaque.

Fixed, thank you for reporting! :slight_smile:

thank you for your quick fix and response
