Did you use all of your seeds up? Seems like a short period for seed potential to die out. I germinated 10 year old vendor seeds last year with near if not perfect results. I'd try them again with a chamomile soak or something, if you have more. I have a couple of 7Pot I haven't grown yet, but not that one, and the seeds are at least 3 years old. Wishing you some luck!
