I'm freaking out...pls help

So I went to my notifications on this app and I checked my comment on something and I saw another account on the same post but a different comment. So it was my profile and I clicked on it and it said "edit profile" so I knew it was mine and it had all the proof it was mine. My original comment was still there. Both comments were posted 5 hours ago as the time stamp says. I'm freaking out can somebody help me? Is this a glitch from the update or something?
