Dear Mishra,
Even if PC 10.0 is installed, it is not recommended to use. The delivered rules from PC 3.0 were only made available in PC 10 to allow backward compatibility for previous users of PC 3.0 who upgraded.
Please, refer to the note below:
1580335 - Customers use 3.0 rules or create their own rules in 10.0
Let me know whether the explanation was helpful.
Thank you,
Fernando
