Disturbing Glitch

[TheGrifter]

Just wanted to know how this could happen and if anyone has experienced something similar.

I was playing on Doyle's Room and while involved in a hand noticed I could see the cards of two other players who were not all in. I was multi-tabling so not sure if I could see them from the start but noticed it on the flop. The hand was 5-handed and I could see my hand and 2 others but not the other two. This has never happened before and I'm wondering how it could. I folded in the hand as did the other two players before showdown.
