PRC VALIDATION DATA FLOW

I need help as I new to applying for DATA FLOW.
I already have my work and school validated on DATA FLOW but my PRC LICENSE was not included on the initial application.

Now I do not have option to add additional document on my first application, so I created a new one to upload my PRC license. Little that I know I do not have option to skip work and school application so I have to upload all of it together with my PRC license.

I do not have the option to just choose PRC license validation only and asking me to pay all 3 documents.

How could I just validate my PRC license for DATA flow?
