Fiction tags

I'm not sure if this is a bug or if I'm just "doing" it wrong, so I wanted to post here instead of the bug section, since I know Dai-kun checks the bug section regularly and I don't want to waste his time needlessly.

When you edit or post a new fiction, there is an option for tags. It says that multiple tags can be separated with a comma. However, when I try to add multiple tags, only the last tag ends up showing.

Anyone know why?

I've tried, for example: romance,fantasy,political -- only "political" shows up

I've tried: fantasy -- only "fantasy" shows up

Can't seem to get more than one to show up as a tag. @_@
