How to remove trash fights and no kills from log?

Went to upload an O2 kill and tried to split the log and find just the kill when it split and I couldn’t, uploaded every single file from the split one at a time and none of them were the kill for some reason, so I just uploaded the big one and chose just the O2 fight, it put the kill on there but it also included all the failed kills. How do I get rid of them or how do I upload just the one specific fight?

I tried importing the parse into act and deleting every fight except that one but it does not save the changes anywhere and there is no export to log file that I could find.
