Well, going through your missing grimoire (using http://destinytracker.com/destiny/grimoire/ps/ZealFire). Your grimoire looks like it's at the correct amount right now (your missing cards add up to the correct max grimoire). There was some issues in the past with grimoire kills adding incorrect points, which may have actually given you the points early (which would explain why your points didn't go up this time. It's an old bug that the grimoire score is now playing catch up to.. Hope this helps.
