Pulling overall boss damage

Been trying to import overall boss damage through the v1 api but the numbers they pull arent the same as what the log itself is saying

They differ in various % amounts and if I try pull a single boss such as Supremus then the numbers are spot on but if I pull only Illidan then the numbers are off again.

This is what I’m using to pull the data atm: https://www.warcraftlogs.com:443/v1/report/tables/summary/zFfJnY1G8rKTkty2?start=0&end=100000000000000000&encounter=-2&api_key=2de02b7e037dec1db4da9934a3859da7
