Filament Stuck On First Time Calibration - Unable to Unload

Did 1st layer calibration for my MINI+ with the sample filament.  Then tried to unload the filament.  It got stuck.  I had to open up the extruder to dislodge the filament.   I see a 'blob' formed at the tip of the filament causing the filament to get stuck.  

Please see attached images.  What is causing this 'blob' and how to overcome the issue?  Thank you.

What I would do is, repeat to load/unload process 2 or 3-times and if I would notice similar trouble, then I would take hotend apart and check inside heat-break -just to be sure it's properly assembled.
But I assume you were just unlucky with this blob (hook) shape.

Mini+ with Bondtech upgrade & modified firmware...
