How to get tags in original case?

Hello everyone, I am a newbie on Hugo, and I encounter a problem during using the template. Firstly, thanks for your commitment on this fantastic website template. On the demo website, for example, this post is under `Space` tag. https://athul.github.io/archie/posts/post-2/  However, on the `tags` page, this tag is shown as `space`. It is automatically converted to the lower-case format. https://athul.github.io/archie/tags/  So my problem is, how can I get these tags shown in their original case on the `tags` page? Thank you.
