Pole Beans - Early Spanish Musica Organic

I'm a fan of Renee's seeds but this Spanish Musica Pole Bean didn't seem to work for me. I have attempted a couple times so far: 1st time I chalked it up to starting too early maybe it was too cold, second time it was warm favorable weather in larger container 4 germinated but two got stuck in their hard shell so only 2 are successful. Currently on my attempt #3 in the starting container indoors buried a little more shallow to get better airflow, because all the rest of the 15+ or so seeds I have sown are either mushy or disintegrated. For Reference (photo) I also bought the royal purple bush bean from Renee as well, they were started before these spanish musica seeds and they are thriving and already producing multiple sets of leaves.
