Stadion banners and loudspeakers at Borussia-Park Mönchengladbach are incorrect

The stadium banners at Borussia Park in Mönchengladbach are faulty. They've had a different spelling for the past three years, and the "For Respect" banner is completely faded or only slightly visible depending on the lighting conditions or the time of the game. This is obviously not correct and should be completely visible like the other banners. Likewise, the large white loudspeakers are not mounted on the roof, but rather the old ones from 10 years ago...see pictures.
