Failsafe showing but stil arms how do i know whats up

on mission planner fail safe is showing. i have it set not to arm on any issue and it does arm, although fail safe still s shows, I went though set up wizard again and checked everything, everything seems normal. I dont want to fly in case it crashes. how do i see what is tripping the fail safe message?

checked battery voltage ect

In Missions Planner -> Flight Data click on the Status tab and look at the “Messages”, “MessageHigh” values which tell you what the last failsafes were.
