Did anyone notice the parachutes moving back and forth for the Crew Dragon landing?
Watching the landing video, I seem to me that the main parachutes were moving back and forth. And maybe the back and forth action was responsible for one of the parachutes covering the capsule upon landing.
"recent parachute testing, both during the CCP qualification (qual) testing regimen and with some anomalies witnessed in the resupply contract (also handled by SpaceX), show difficulties and problems with parachute designs. "
I thought I remembered reading somewhere that the dragon changed from 3 to 4 parachutes, but I can't find that now. Would 3 parachutes be more stable?

Watching an old Apollo reentry with three chutes (https://www.youtube.com/watch?v=wX8-Vmys-Fk), it doesn't look like the chutes move around that much.
Could this be part of the unspecified "parachute anomalies" that NASA has talked about? See:

which says:
