Layon issues with gallery

[woile]

Using the theme lanyon, when accessing to /galleries a list of galleries is displayed, but the last slash (/) of a gallery is replaced with the url encoded value %2f.

For exmaple:
/galleries/my_gallery/
is replaced with:
/galleries/my_gallery%2f

And when clicked the gallery is not correctly displayed.
Also the colorbox plugin doesn't seem to work (but with the bootstrap template it does).

I've been trying to fix it but I'm not quite familiar with nikola yet.

Thanks.

Edit: I think this issue also affects the nested links.

Edit2: Sorry I just read the known issues for the theme:
Known Issues:

• Galleries will work better when Issue #1764 is fixed.
• Submenus in navigation links are not supported
