QLMarkdown is not working on file icons

[TatsuhiroC]

I use Typora as my md editor. However, i met a problem that there are two different file icon in my mac.

The upper one is the default icon of Typora, i love it.

But the newer files have the lower one, the ugly and created by Typora app icon by mac.

I want my md files have Thumbnail icons. I used QLMarkdown and killall Finder to reset. Its not working on the icons. what should i do?
