Removing add-ons does not change the problem except that one of the planes it happens in is an add-on.
I am not using Developer Mode.
The logbook does not record take-offs and landings when they are done on the water with either the Icon A5 or my third party amphibious C172 with floats. It records the flights, times and duration but not take-off or landing.
A screenshot would not add anything useful.
Fly a plane capable of safely operating on water and take-off and/or land on water.
