First year gardening, central Wisconsin, planted tender green improved bush beans and new growth on the plant looks good, but after a while they begin developing these spots and the leaves begin to die, I will include pictures and hope someone can tell me what’s going on and what my options are for containing this or if it is normal. TYIA!

Most likely sunburn. It occurs when strong sun hits wet leaves on a dewy morning or after rain. It can occur at any time but younger leaves are more susceptible.
Parasitic diseases are the standard suspects with regards to brown spots on Normal Bean leaves. Aspergillosis and rust are normal guilty parties, with the last option frequently leaving an obvious orange or tanish dust on the underside of leaves
