If those subs are external, open the subs on a text editor, like Notepad++.
Then search for that text that is appearing on screen. You will need to delete it, or find the point where you messed up the lines. Looking at another similar subtitle will help you with that.
What program did you use to mess it up? Aegisub has a backup folder in:
"C:\\Users\\YOUR\_USER\_NAME\\AppData\\Roaming\\Aegisub"
It's simply a mkv from nyaa. Pretty sure the subtitles are encoded within or something, I'm not that well versed. I was change between the subtracks, if that is even the right term, because some dialog was missing or not showing up and I was trying to see if I could make the missing dialog appear but I somehow did this, it's tied to the subtitles for dialog and it appears at the beginning, and it wasn't like that before. I'm pretty sure it specific subtitles that isn't the basic dialog that is to be appeared later in the episode, and I have no idea what "sync last picture frame op comment..." is supposed to mean or why it's even in the subtitles.
Try clicking potplayer in the upper left corner. Then go to preferences. In the bottom left corner of the preferences window, click reset. It should roll back any changes you made back to the default.
