twisted coyledons with yellowish areas?

[gardenpaws_VA]

I'm growing an assortment of varieties this year, some commercial seed and some saved seed, and everything's fine except for the "clamshell" of Jaune Flamme. That variety, ONLY, has slightly distorted seed leaves, and they aren't a nice even green like the other cultivars.

These are seeds I saved from last year, and I did have a wilt problem on some of my JFs last year. However, these seeds came from late fruits on the plants that had survived, and the seeds were (I believe) properly fermented.

Should I just give up on this batch of seeds, get some fresh seed from another source and start over? I'm keeping that variety away from my others, just in case, but will shortly start transplanting as the different cultivars get big enough.
