And it reads that the imported file has more than 1 certificate
When you import intermediates via the GUI, then you need to upload the
intermediates one by one. So open it up in a text-editor and split it ,
so that each textfile you want to upload contains just one intermediate.

Even with missing intermediates your server should not be vulnerable to
the "Drown"-attack, as SSLv2 and SSLv3 are disabled since long. Which
analytic tool reported the "Drown"-vulnerability as present?
