Why do coffee grounds keep showing up in my brewed coffee?

"A lot of times, this is caused by the paper filter not sitting in the coffee maker correctly.The easiest way to fix this is to buy a reusable filter. The reusable ones don't ever have issues like this. If you don't want to do this, I was always told to flip the paper filter inside out before installing in which helps it stick to the walls of the basket.

I have a reusable coffee filter and I am having this issue. Ive cleaned the pot, made sure the valve is clear and working, and still can't figure this out. I would definitely not say reusable filters are the 100% solution, but they are handy.
