Sudden loss of Ruleset and missing LAN Interface

Hi

After a reboot, i find the LAN Interface eth2 went missing.

Also, the Firewall ruleset i created went missing.

I downloaded and checked the config.boot file. It's all there.

First i thought its some GUI issue, as the LAN interface is working.

However, the Customer Firewall Ruleset is not working though it is available in the config.boot.

I restored the config but the problem still remains.

What is happening?

Note: Prior to reboot i was creating some rules: http://community.ubnt.com/t5/EdgeMAX/Block-Streaming-Media-Sites-without-affecting-the-Traffic-of/m-p/1665291#
