Selecting a single device in policy-based routing

Hello everyone.

I'm trying to add a policy-based route like:

• Matching: a target list (Netflix domains)
• Device: SmartTv
• Interface: VPN

The issue I am having is if the device I want to select is already a member of a group, I cannot select it individually. App only allows me to select a group, or a device which not already a member of a group.

I tried a workaround like removing the device from the group, creating the route by selecting the device individually and re-adding the device to the group. It seems to be working, but I suspect it is a bug, or I am missing something here.
