Alpha & others effects are not use in haxe using SWF

Hey Everyone,
i’m a french student and i work on a personal game using haxe & openFl.
I recently add alpha animation on my sprite, but the animation doesn’t work :frowning:
I add a glow effect too, and it doesn’t work too. Is it normal ? How can i patch this please ?
Thanks !

ps: my version of openFl is the 8.6.9
