Hello,
You can just add --line-numbers at the end of the command you use to see
the results you posted and then use iptables -D tableName ruleNumber, i.e.

iptables -D OUTPUT 5

HTH,

iptables --line-numbers -t mangle -vL OUTPUT to verify rule numbers, 
then just delete whatever you need with -D, i.e.

iptables -t mangle -D OUTPUT 12
