Only the top business rule will run against my request

Only the top business rule will run against my request

Hi, I have set up business rules to:
1) assign a request to a group based on the category and sub category
2) assign a priority to the request based on the category
 
If I have rule 1 at the top it works fine and assigns the group but the priority is left blank
If I have rule 2 at the top of the rules list, it assigns the correct priority but no group
Can anyone ofeer some ideas please
