I can reproduce this.
After first import and not title (Ohne Titel), I did the same procedure an took a scrreenvideo.
Maybe you see something, I did on a wrong way:

ScreenVideo and settings

1: Klick on Import
2: Choose Dropbox
3: Navigate to the Song
4: Activate Checkbox
5: Click on OK
6: Set ok to Import Settings (Filename as title)
7: New Song has no title (Ohne Titel)


Update: I could find out the trigger for the problem. 
Settings - Import Settings -> PDF-Metadaten extrahieren
When this is active, the title wouldn't be taken as shown in the dialog preview from the name of the pdf.
I think it could be a little bug

Question: What kind of metadata from pdf-files would be mapped (an to which fields), when activating this option?
In the manual there is no description for the option "PDF-Metadaten extrahieren" (extract pdf metadata).
Is there an information about that setting in deep? Tx

In the link above there is a screenshot too from the settings (because my iPad runs on german) so that you can see, what I mean...
Tx.
