Peplink Balance One - Per Vlan MAC Table?

Does the Peplink Balance One maintain separate MAC forwarding tables per VLAN or a single table for all?

We have 2 VLANs set up on different ports with InterVLAN routing disabled.

We have 2 devices with the same MAC address, one on each VLAN. The devices should be isolated from each other, but packets to each device appear to be dropping. If the Balance One has a single MAC forwarding table independent of VLAN, then that could explain the issue.
