[RAM Concept] Shear Reinforcing Program Bar: Spacing too tight

Hi, 

I'm have several spots where the software is detailing stirrup bars that does not seem to make sense. I've looked into the capacities vs demand and it appears to me that stirrup should not be needed or to be provided as code minimum. Instead, the program seems to be detailing it at a very tight spacing. 

I've included the final generated reinforcing and also the design strips that were modeled. Could you let me know what may have the program to require more bars that necessary? 

Thanks,
