A problem with battery DC capacity (Residential PV-battery Model)

I'm having a problem when calculating the total battery costs at the system costs page in the model: Battery Storage, Detailed PV-Battery, Residential Owner. I have calculated the desired bank capacity and the desired bank power with REopt tool, and I have obtained an optimal result of 49 kWh and 8.499 kW. The problem is that when I go to the system costs page, in the battery DC capacity it appears a 0, instead of a 49 (which is the capacity I want) so the system does not calculate properly the total cost asociated to the battery (as you can see at the picture). It is not posible to change the and I have  tried to change the bank sizing from set desired bank size to specify cells  and  the 0 doesn´t change. 
Do you know how Ican solve this problem? 
Thank you so much!
