Only one keyword linked per post

Hello,
This plugin is pretty great, really helpful.

I just install it and setup some keywords and I notice that only one keyword linked per post.

like this post
https://www.williamtai.moe/villa-fontaine-%E6%B1%90%E7%95%99/

I set a keyword record as “Villa Fontaine” and linked to
https://www.williamtai.moe/tag/villa-fontaine/

but only one keyword has been linked.
Villa Fontaine
