I just noticed that some of my messages in GMail are getting labeled with newly created labels like

eb gc hb na remove S Wa X

And I have never created them before.

I instantly checked my account for any illegal activity and I see that no one apart from my ip is accessing the GMail and so it looks like a glitch from GMail only.

Has anyone seen something like this?
