Fail2Ban unbans after 10 minutes. bantime none warning?

having a bit of an issue with fail2ban filters, for some reason it unbans after 10 minutes even though I set the ban length to one year. Could you assist a brother out?

jail.local declaration for filters:

[nginx-proxy]
enabled  = true
#port    = http,https
action   = iptables-multiport[name=NoProxy, port="http,https"]
filter   = nginx-proxy
logpath  = /etc/nginx/logs/*access*.log
bantime  = 31536000 # 1 year
maxretry = 0

[nginx-shellshock]
enabled  = true
#port    = http,https
action   = iptables-multiport[name=ShellShock, port="http,https"]
filter   = nginx-shellshock
logpath  = /etc/nginx/logs/*access*.log
bantime  = 31536000 # 1 year
maxretry = 0

nginx-proxy.conf

[Definition]
failregex = ^<HOST> .* "GET http.*
ignoreregex =

nginx-shellshock.conf

[Definition]
failregex = ^<HOST>.*\(\s*\)\s*\{[^"]*\}\s*\;[^"]+.*

ignoreregex =

Here is my fail2ban.log file

2015-10-27 06:21:48,953 fail2ban.jail           [8319]: INFO    Jail 'nginx-auth' started

On fail2ban service restart, I also get an error about shellshock bantime being set to none:

2015-10-28 00:29:31,351 fail2ban.transmitter    [11600]: WARNING Command ['set', 'nginx-shellshock', 'bantime', 'None'] has failed. Received ValueError("invalid literal for int() with base 10: 'None'",)

Greatly appreciate any help, thank you.

The entire issue was dedicated around me using the comment tag, which apparently in fail2ban configurations comments the entire line. Either change the hash tag to a semi colon or put it on another line.
