Small issue with "Animate aircraft"

Hi,

When I disable "Animate aircraft" it comes back on again after a while. The switch is still "off", but after a while the aircrafts become animated again. I have to change the switch to "on" and "off" again, to disable animation.
I've tried it with two browsers (firefox and chrome), so i think the error is not between screen and chair.

Kind regards and happy holidays
