Anet A6/Ultimaker Cura - Underextrusion

I have a software problem with Ultimaker Cura 3.5.1. Whenever I slice an object and transform it into G-code, the printer (Anet A6) prints a very soft and frail element. The lines the printer creates are far too thin so they do not stick to each other. The object looks like a sieve. It must surely be an underextrusion issue.

But when I use Cura Lulzbot 3.2 software, the problem doesn't occur. I upload the same STL object, use the same printing settings and the effect is perfect while using Lulzbot. I've checked all the options and they seem to be exactly of the same value.

When I compared the G-code files I found the following difference:
G1 X125.626 Y34.962 E214.50701 - Cura Lulzbot
G1 X127.399 Y19.944 E0.00185 - Ultimaker Cura

The "E" (extrusion?) value has five orders of magnitude difference. It is like this throughout all the file.

Could you please help me with this one? Where do I make a mistake? If you want, I can upload G-codes and photos of both the softwares makes.
