Sort series on Kobo Aura H2O

Hello,

I'm trying to sort series by books but it seems I'm unable to do so on my Kobo Aura H2O. I'm using calibre with the Kobo Utils 1.8.1.

I used the "Order Series Shelves" option, and I set the series ordering to last added. I also see the series title and index in the series list (see picture) but I can't get it to sort the right way. Can anyone help?

I hope Kobo will add better series support sometime in the future. :(
