Some beans just don't want break. I have bunch of seeds which didn't germinate, but all they were in the same container as the two seeds which germinated. You can check in my journal, I was discussing about this. From 6 only 2 in the same conditions. And more examples like this. They're just old seeds and you pay for nothing. That happened with some Mephisto, some Fastbuds, some Green house seeds etc... Great sellers will pay back or offer another seeds... and some sellers even will not reply.
