State color of buttons in Entities Card

I’m a bit confused about the state colors of some buttons in an Entities Card. There are 4 cover devices (3x curtain, 1x shutter) in this card and I’ve added some preset buttons for two of them. When the covers are open state color = yellow, when the covers are closed state color = blue. However the preset buttons I did configure only change state when covers are open (yellow), but when the covers are closed they turn grey (expecting blue). I like to have the buttons blue also when covers are closed, did I miss something in the card config ?
