Internal Network Firewall Rules for single LAN

I inherited a Peplink Balance 380 firmware 7.1.0s081 build 2363 running a single LAN on a 255.255.255.0 address space. I have separated the devices into subnets within this address space for easier management via Internal Network Firewall Rules, however it seems Rules only apply to LAN-site-to-site-VPN connections, and inter-VLAN connections(though I cannot confirm this yet).

I have the following 6 rules set

The first rule does not work.
The 2nd to 5th rules work fine.
The 6th rule appears to do nothing.

Do I need to create separate VLANs or am I just missing something?

Any comments/feedback will be greatly appreciated.

Firewall rules only will take effect for Layer 3 and above network traffics. Detail explanation please refer to the URL below:
