How to generate variations from imported custom phrases with Factory?

In the Factory, I can generate new variations from a phrase I created using the different settings offered in this section. However, when I import a MIDI file which is also a phrase from my own library via drag and drop and place it in my library I created in Synfire, the app starts to analyse this file displaying many parameters like tempo, signature, length, key, scale from the original midi file etc.. but it doesn´t generate new variations from this imported phrase.
As soon as I select the imported new phrase and click on the "generate new phrase" button, it doesn´t use the phrase settings from the midi file but generates a phrase from the last used settings. 

I have many custom phrases that I have created over the years in my projects, mostly piano phrases and chord progressions and I would love to use them as the basis for new variations using Synfire Pro Factory.

While studying the manual, I came across the following chapter:

Figure Recording

Figures can be recorded by capturing incoming MIDI messages into the Take parameter and then running Figure Recognition on it.

Is this the right approach? I have successfully established the connection between my DAW (Bitwig Studio) and Synfire, but I am unable to record any MIDI data. I have placed a MIDI Drone in a Bitwig track along with the MIDI file I want to record in Synfire, but it is not working. 

Any help is appreciated
