Display not working while in manual mode.

i've been testing my camera (a Nikon D3200) by filming with various shutter speeds (from 1/30 to 1/1000). And after that, I noticed that in manual mode, the shutter speed, iso, and aperture got stuck. Shutter speed at 1/400, iso at 200. It just doesn't change when I use my buttons. In auto mode or in any other mode except manual, it does change automatically. I've reset shooting and setup settings to default but that didn't help. Also I removed the battery and lens for a few hours and tried again but that also didn't work.

I hope this video will make easier for you to understand my situation. https://www.dropbox.com/s/8o5jf4z7ngvmob...
