[BUG] ext.commands: Executed Twice

What happened?

I created a new cog (loaded) like so:

from linelib import Client as ClientType
from linelib.ext import commands

class CogDemo(commands.Cog):
  def __init__(self, client):
    super().__init__()
    print('inited')

  @commands.cog_command(name="test")
  async def test_command(self, ctx):
    await ctx.reply("Test.")

def setup(c: ClientType):
  c.load_cog(CogDemo(c))

...and the bot replied correctly.

But what I saw this on the console:

I believed that the request was probably sent twice, and I still cannot find where exactly occurs this sort of error.

Yes, I'll need to revise the ext.commands module.

Just to make sure...

[x] I've checked other issues, and this is not a repeated report.
