Logs not showing DPS Numbers correctly

While I was running Heroic NYA for parses, I ran into an issue with logs and parses not showing my total dps which resulted in a lower parse. I will attach images of my dps from the raid that show my overall dps as well as damage done for boss. I will also attach my logs to show the numbers for that boss. What is causing this issue and how can it be resolved to show my total over. It has done this for several of my boss fights including H N’zoth where it showed me doing about 5k less than what I did. These fights showed a lot higher numbers being left out.My Character is Cubbers-Stormrage.

Nzoth excludes damage to synapses that heal to full, and then overkill is also excluded.
