Attach USB to boot-partition gets Error

[gurragurra]

Hey there,

I'm currently familiarising myself with FreeNAS and loving it so far. I have run into one problem though.

I have 2 identical usb-sticks. One has FreeNAS installed and I want to mirror the other one. I'm trying to attach it through /System/Boot Environments/Attach. I can choose the other USB-drive as a member disk but when I press save this message pops up:

-----
Attach Device
'async for' requires an object with __aiter__ method, got generator

Close
-----

I've been searching for the error message but all I find is a lot of Python discussions. I know nothing about Python so I'm a bit lost right now.
Any help or suggestions would be much appreciated!

Version: FreeNAS-11.2-BETA3
Motherboard+CPU: ASUS C60M1-I
RAM: 2x4GB
USB sticks: 2xSanDisk Ultra Fit 16GB USB 3.1

/Cheers

Known Issues
Due to a regression, it is currently not possible to mirror the boot device. This will be fixed for RC1.
