Interior Panel Lights Turn Off When Going To Exterior Mode and Back

Hello Team, My plane I have made now has an issue with the interior lights
(panel lights and interior spot lights) turn off when going to exterior view
and back to cabin view. The lights must be switched back on. Do you know of a
fix or haven an idea why this is happening? It didnt used to do this, and now
it does. I use Panel Lights, Cabin lights, and Identification lights. Either
‘and’ all of them switch off when going to exterior view and then back to
interior, requiring one to have to turn them back on again. The NAV lights are
not effected. Many thanks for any input. Bill Ortis Lionheart Creations Ltd.
