I built a Simulink model and from a certain point, where I don't exactly remember my commitment to that, one subsystem is framed by a red line and the background turned yellow. Please see screenshot attached. Because of data policy I had to pixelate some parts...
There is literally nothing displayed that reveals anything of the cause for that. Taking a look inside of that subsystem, there is everything as usual with respect to the colors. As I seem to be the first one in this company having that problem, noone other knew a solution, nor I was able to find a solution using searching machines.
Despite the simulation still runs, I would be extraordinarily glad to get rid of that suspicious red box. Any help is appreciated!
Best regards, Patrik
