1) If you migrated data over and the variety you needed wasn't there, you selected "unknown". Some of these varieties are here now, and users are unable to go to inputs >seed inputs> edit the seed and change the variety. This needs to be done!
2) If you pick the wrong seed variety by accident not only can you not add it again, but you can't change it.
Hi, you can add and edit the seed input variety after migrating data. Thanks!
