Hello, I was wondering when I brighten the run in Premiere Pro and some white bits in my screen are ''over saturated'' is it a problem? Or do I have to tweak the settings for everything to be clear?

And I'm going to ask another thing, my load remover doesn't work, can someone help me with it?

Edit: Here are pictures of one dark part of the run.
