Should you delete waterfall releases?

I did the waterfall release move for an EP. 6 songs, one song each month, each single release includes the previous single. The EP is fully out now, leaving me with 6 singles and the EP itself in the discography on spotify. My understanding is that, because the ISRC codes on each song/the song files themselves are the same across each single drop, the waterfall singles can be removed safely without losing streams (and the cover art shown in the top songs list would default to the actual EP art). I am TERRIFIED that I will mess things up in doing this, but find the list of releases to be a bit confusing/overwhelming now. I'm releasing through distrokid. Can I safely remove the waterfall releases without comprimising analytics?

Sorry if this has been answered before, I've had trouble finding anything specific.
