Minecraft Website Mob Vote Error

So.. I was trying to vote for a new mob in Minecraft Website, but it didn't work. May I wonder know what's the issue? Or its just a bug? If it doesn't work, should I use bedrock edition instead? I need to vote right now before Minecraft Live started. If it almost time, I should use bedrock edition instead. Is anyone has that same problem? Or is it just me? I don't know what to said to that error.
