Google Search Doesn't Update My Youtube Channel Name

Hello everyone, I have a YT channel called Dota Center (It was The Game Zone before but I've changed it). I tried to find my channel on Google but could not. My channel ID is UCFkQelXVTAVBVbXyKqHfJ-Q. I searched this ID and i saw that Google search shows my old name yet. The cache has been updated on 17 December and since that it does not update. I have active channel, 45+ videos and enough views. Daily uploads. My channel deserves to be updated (at least from 17 December til this day). So my question is, Google updades the cache auto but is there any way to request for a -cache update- or whatever? Thank you for your respones already.

Here's the 2 screenshots:

you can submit the url here and hope they recrawl it.
