Collecting data and Response file

In Acrobat 10 and 11, when I received a completed form, I just double click on the attachment and I'm asked to "Add to an Existing Response file". After I clicked the OK button it opens the response file and display all the responses in a spreadsheet format. However, now in Acrobat DC, it opens as a full pdf file where I click on each pdfs in the left navigation panel to see the responses (btw, the "Add files" and "Create Folder" buttons are ghosted). It seems that to see the responses in a spreadsheet format, I have to:

1. download/save each completed form, then
2. Open the original form
3. Click Prepare form (in the right panel)
4. Click More (in the the right panel)
5. Click Merge data files into Spreadsheet
6. Click Add files (to manually add every saved completed form)
7. Click Export
8. Select CSV as the format
9. and then click Save

Now, this seemed like a very long and complicated method as oppose to the Acrobat 10/11 method. Is this the only way or am I doing it wrong??
