Battery Charge Percentage and Stored Energy don't match

I have a Goal Zero 1500X. It is updated to the latest firmware (1.8.9).

When I look at the app, the charge percentage (%) and charge remaining (Wh) values don't seem to match. I am currently seeing 76% state of charge, but only 990/1500Wh (66%). Why does this happen and is there a way to make it accurate?
