Slider for LVM2 is only allowing 1TB increments

Hi guys,

I'm running 0.3 AMD64 version of OMV.
I ran the any updates available in the WebGUI
Installed the LVM2 plugin
Created my RAID (4x2GB Raid5)
Created both the Physical and Volume groups.

When trying to create a Logical Volume, the WebGUI slider only lets me chose 1TB increments. I cannot manually set to a smaller size.
Is there some way to change this or do I need to create LV at the cli?
