ENDIAN Firewall - Firewall blocking traffic via "BADTCP"

I cannot seem to find anything about this out on the internets so I was hoping someone here might shed some light. I am having trouble with a particular host. It seems to be having connectivity issues to the internet (local connectivity appears to be fine) and if I watch the logs I will see a lot of this.

2015-11-15 18:49:53 BADTCP:DROP TCP (br0) 192.168.1.109:63943 -> 184.25.63.40:80 (eth5) +

I would like to know what causes "BADTCP" so that I can attempt to rectify that issue. My first thought is the TCP headers/flags are violating some built-in rules but without knowing for sure I just cannot address the issue.

Thanks in advance.
