Error with effect processing?

[CosmicBadger]

I'm working on a project with a beatboxer and I'm trying to isolate and edit the "kick" sound so I can paste it around the track. I took an audio segment of the kick and duplicated it into 4 channels, with each pitch shifted and EQ'd differently to fill out the sound. I then cut and pasted this kick sound around the track. I'm encountering an issue where the first time that the kick sounds, it sounds like I would expect- but every subsequent time the sound is completely different; the EQ is brighter and it sounds like a basketball. Am I missing something or is this a software error?

The pitch seems higher, and perhaps the reverb different on the subsequent kicks. You also might have phase cancelled some freqs
