GTS glitch?

[Shiny Noctowl]

I was cloning a shiny Mew on the GTS. When I went to take it out, its name was Myuu (in Japanese) and its species was MEW, just like it should have been, but it was holding a Chesto Berry, its sprite was an egg, and when I pressed A, it said, "Do what with this ARTICUNO?". I waited a bit and came back, and the Mew was normal. I've cloned this Mew in the past and it's never happened before. Is this a glitch with the GTS, or is my Mew hacked?

Sounds pretty weird, but it might be related to the morphing glitch detailed [bp=Global Trade Station#GTS_morphing_glitch]here[/bp].

I'm going to put this in Video Games, but one time I put something on the GTS and checked it right away and it turned into a Vileplume holding a Town Map. Checking it a few minutes later it was the thing I had actually put up (I think it was a Farfetch'd). And that's just putting it up normally, without cloning.
