I've tried for some time to fix my problem alone, but now i need some help ! ( 1.16.4 version ) I am making server with friends using custom items and powers related to them, in this example it's a wand of levitation. So here's the command that I've used :

execute if entity @a[nbt={SelectedItem:{id:"minecraft:stick",tag:{display:{Name:'[{"text":"WAND OF LEVITATION","color":"gold","bold":true},{"text":"","color":"gold","bold":false}]'}}}}] run effect give @s minecraft:levitation 1 3 true

This isn't showing me any error, just not applying the levitation effect. why ? Command block on Repeat-Unconditional-Always active Here is the Item
