Error while trying to edit an item.

When I tried to edit this potion, an error occured.
It wouldn't let me open the NBT editor.
It does allow me to open the SNBT editor.

Here is the potion give command btw: {Count:1b,id:"minecraft:potion",tag:{CustomPotionColor:16645562,CustomPotionEffects:[{Amplifier:1,Duration:800,Id:1},{Amplifier:2,Duration:800,Id:3},{Amplifier:9,Duration:2000,Id:5},{Amplifier:9,Id:6},{Amplifier:9,Duration:3000,Id:10},{Amplifier:4,Duration:1600,Id:11},{Duration:2000,Id:12},{Duration:2000,Id:13},{Amplifier:4,Duration:2000,Id:21},{Amplifier:9,Duration:1600,Id:22},{Id:23}],display:{Name:'"God Potion"'}}}

Update, it seemed to be a one time thing. It now seems to work after reopening the game.
