I know this is an old post, but I was also seeking the same information for assistance with filling out the PMI ACP application.
I found this link today and it includes screenshots, which I found helpful. I was also concerned about filling in the General Project Experience section as I already have my PMP certification, which meets this requirement.

According to the screenshots, once you enter the Agile experience, I guess PMI already recognizes if you're a PMP holder, so no further info needs added. That's where I was getting confused.
Hope this helps.
