Changing bg_color of a label not working

[Nisbo]

I just started with openhasp. So far its working with Home Assistant but I have a small problem.
I am not able to change the bg_color of a label.

{"comment":" ----------- Page 0 layout ------------"}
{"page":0,"id":1,"obj":"btn","action":{"down": "page prev"},"x":120,"y":290,"w":79,"h":32,"bg_color":"#2C3E50","text":"\uE141","text_color":"#FFFFFF","radius":0,"border_side":0,"text_font":24}

"bg_color":"#FAE10C" for the ids 51, 52, 53 does not has any effect.
Any ideas ?

for "obj":"btn" bg_color working but align is not working, its always centred

{"page":1,"id":52,"obj":"btn","x":50,"y":0,"w":180,"h":35,"text_color":"#000080","bg_color":"#FAE10C","text_font":32,"text":"Ziel","align":"left","radius":0,"border_side":0}

UI Theme is "Mono"

Simply add "bg_opa":255

{"page":1,"id":51,"obj":"label","x":10,"y":10,"w":50,"h":35,"text_color":"#FFFFFF","bg_color":"#FAE10C","bg_opa":255,"text_font":32,"text":"##"}
{"page":1,"id":52,"obj":"label","x":60,"y":10,"w":180,"h":35,"text_color":"#FFFFFF","bg_color":"#FAE10C","bg_opa":255,"text_font":32,"text":"Ziel"}
{"page":1,"id":53,"obj":"label","x":240,"y":10,"w":230,"h":35,"text_color":"#FFFFFF","bg_color":"#FAE10C","bg_opa":255,"text_font":32,"text":"Abfahrt"}
