The total capacity with a filter change IS 1.4L. So if you added that, you should see it on the window, and likely will be overfilled by 200-300mL since you didn't change the filter.
My guess is you're incorrectly checking the sight glass with the bike on its side stand. In which case, it's going to read way low because you have to check it completely upright to get the proper level.
Tis better to be thought a fool and remain silent, than to open one's mouth and remove all doubt.
