Bugged Krosos M log

Yesterday my guild and I killed Krosus on mythic difficulty but after uploading the file seemed bugged.
Here’s a direct link to the fight - https://www.warcraftlogs.com/reports/9jvg1LV6Hc8pCJRD#fight=31
As you can see, it says the fight lasted 7 min + and our healer (Monclaire) was casting mass ress 10 seconds into the fight.

Here’s a link to where the fight originally started - https://www.warcraftlogs.com/reports/9jvg1LV6Hc8pCJRD#fight=31&start=4963457&end=5300671&type=healing

Is there any way to fix this? The entire file is there from start till finish.
