Dropdown not selecting appropriate value

Hi Guys,

I am trying to automate a drop down pairs below where I need to select some key:value from both set of pairs but when it comes to second pair drop down, it is “not” changing the values as described in the select activity but it is over riding in the first pair of key:value.

Note : the parent class is same for both the drop down pairs and - sign is to delete the drop down pair from the list.

Please help

Thanks & Regards,

could you please share your workflow/selectors?
