EP's that are actually albums

I noticed a lot of albums being put in the EP-section, wich actually are albums. But I couldn't find a way to fix it. Can someone please fix this.

My question is also: why are these albums put in the EP-section? I know that 90's people regard albums that are shorter 40 minutes to be very short, but albums are supposed to be 30 - 45 minutes. That has always been the case.

Thank you.
