I contacted them as you said. The solution they provided is:
Cura implements too much retraction in the end Gcode, which causes the heated filament to clogg the nozzle.
This code has to be changed:
G1 Z+0.5 E-5 X-20 Y-20 F{travel_speed}
If the segment E-5 is removed, there will be no extra retraction and so the nozzle should not get clogged.
I am going to test this on my next print and see if this is indeed the solution
