Copter runs way faster than the speed set in auto mission [solved]

ArduCopter Copter 4.0

It’s a decent quad. Black Cube, Herelink, 400kV motors running 16’ props on 6S.
The Cube is not hard-mounted, but the damping solution is pretty stiff.

Problem is, it won’t run missions properly everytime.There’s 4 logs in the attached archive. The first two missions were run without a hitch. The third, which is covered in the last two logs, as I gave two attempts at, is where the problem arises.
Camera gets triggered very fast during the accelerating and slowing down portions of the flight, while the drone shoots to 13 m/s even if the mission was set to 6 or 8 m/s horizontal speed.
It can be something as simple as the SD card malfunctioning, but maybe someone encountered this in the past and can point the culprit faster.

[Solved] Found the culprit(s). Pre-designed missions, made on three different laptops, of which one lacked the checkbox for “use this speed for the mission”. Coupled with a weird setting for WP_NAV_SPEED of 1400 cm/s, and a camera that would refuse to trigger if triggered too fast.
