Text Display shifted to the right

The test includes two players. The first has the texture pack with the Admin image in it, the other doesn't have this texture pack active yet.

I place a command block and then enter the following command:

/summon minecraft:text_display ~ ~2 ~ {billboard:"center",background:-2147483648,shadow:true,see_through:false,persistent:false,alignment:"center",text:{text:"",extra:[{text:"\uE810",font:"donuts:default"},{text:" "},{text:"Dxmdaam",color:"#960d36"}]},transformation:{translation:[0.0f,0.0f,0.0f],left_rotation:[0.0f,0.0f,0.0f,1.0f],right_rotation:[0.0f,0.0f,0.0f,1.0f],scale:[1.0f,1.0f,1.0f]},Tags:["player_display"]}

Then the text display appears AND there are no issues there. BUT when I use the second account AND activate the same pack as the first player to be able to see the Admin image on the text display, the text display shifts to the right, and I don't understand why. I'm using 1.21.4 and I tested it in vanilla 1.21.7 and I have the same problem.
