Need help making sense of my NEM credits

Hi all, Im having a hard time understanding how to read/make sense of my SDGE (understand that this is done very much on purpose). As you can see on my latest bill, my solar system has produced 970kwh which apparently works out to $240.46 in NEM credits in the CCA generation calculation section(my cumulative NEM credits for the year are $535.26). But then when I look at the NEM summary page, I see my cumulative remaining credits listed as $1300.94. Can someone please tell me what the difference is between "credited to NEM balance number"/"cumulative NEM Balance credit" in the CCA generation section and the "remaining credits" in the NEM summary section is? Why there is a discrepancy in those numbers? And finally, which of these amounts will be returned to me when I true-up?
