Subscribtion section full with unrelevent content

I am subscribed to lol esports on youtube, because i watch some EU and NA LCS. I however do not watch any lpl, but my subscription page is filled with lpl games, streams etc. This resultst in having to actually search for other videos from channels that im subscribed to.

My question: How can i remove getting videos in my youtube subscription box from regions i dont watch. (Lpl vids)
