You have set SMB v.3 on HiMedia in WHAT? In KODI or in that Wrapper, or both? There's no setting for SMB protocol by default in the Settings or in the factory Wrapper. It could be because you're not using the factory, rather that other Wrapper. I guess it won't work with the factory one, only with SMB v.1.
Just for curiosity, if not only for this, why are you using that Wrapper anyway, what's good and better compared to the factory Wrapper?
Set in Kodi (as I stated in the original post!). I have removed the HiMedia wrapper app from the Q10.
I use the alternative wrapper because it has a far better interface than the HiMedia one.
