Genre / Tags not showing in mixed content?

[RKTWX 0]

I am setting up my libraries, hosting the Emby server from a Raspberry Pi.
I will mostly use the genre and tag sorting, and on my Roku, both are showing good under the sections Movies and Television.

But I have also have a library with mixed content. I can see on my Roku perfect the things that are in this library, but when I want to show them by genre or tag, it says there is nothing to show.. When I open Emby through my browser, it also shows perfect, and both tags and genres can be viewed perfect without this error message.

Is this an issue on the Roku?

Hi. That isn't suppposed to happen.

Can you show us a screenshot of what you mean? Is would help show us if this occurs when using tabs or buttons. We will then get that fixed. Thanks.

Hi.  Make sure you don't have any filters engaged.

Here are the screenshots from my browser. As seen, I can see both the genre sorting and the tag.

The last picture is from my Roku, where 'tag' isnt even seen, and where genre shows up completely empty.
@ebr : I don't see any option for filters in the menu

What shows up inside those genres?

I have 3 things inside those genres. One anime, one dutch TV show and one documentary. 

All 3 shown perfect, except on the Roku. I can see them on the roku as well, but only under the tabs "shows" and "folders"
