Hardcore (rock) and hardcore (electronic) being the same

Hello! I wanted to let you know, that if you go into “genres”, and then go into hardcore, you will see that the artists mentioned in the genre are a mix between hardcore (rock) and hardcore (electronic music). These two are insanely different, and it messes up stats, and this is due to the label being the same for both of them. I know its very confusing when there's two genres that are called the same though
