Could it be an issue with your schedules? Both reports you mentioned are only for zone sizing and not for the hourly simulation.
To check the if the hourly simulation has internal gains applied, I think the easiest way would be to change the OutputControl:Table:Style from HTML to CommaAndHTML using the IDF editor or a text editor and rerunning the simulation in EP Launch so you can produce a CSV file.
If you are comfortable with python, you can open the SQL file following this discussion on unmet hours: Alternate ways of opening an E+ .sql file - Unmet Hours
