B&M shifter not catching gear?

B&M star shifter.. Having issue of this part >see arrow< fully seating into the 1st gear notch (circled) and slips right out when I shift into ratchet gear or even just 1st gear. Is there something out of adjustment? Or is it just worn out? This is an all of the sudden issue. TIA
