So I was replay making on my alt account(Or atleast trying to)

I was editing the replay, and it suddenly just cut out a major part of the replay and skipped to a point in time after the opener.
This didn't happen until the 30-40th time editing (I edit too much).

I have the end result of what I tried to do but was ruined. Is this a glitch, or can I fix this?
Replay's in attachment if anyone wants to look.

Extra details: I also think that the first kick that my tori was supposed to do was for some reason, skipped into the ending. But the ending I originally made didn't go in properly.
I'm using version 4.31
