ASM extracting wrong Parameter name

Hi, Urgent

 

I'm doing ASM POC, I see ASM is not properly extracting learned parameter name. like there are 3 different parameter areurl=1213232, areurl=sdwewqeq, areurl=1213fdeer. all these 3 are different parameter in learned parameter. As per my understanding parameter name should be only areurl and anything after '=' should be parameter value.

 

Please correct me if my understanding is wrong.

 

If asm is not properly extracting parameter name how can i correct this.

 

Thanks, Sachin
