Ultimaker Owners

I am trying to print a simple part and the printer seems to print extra lines toward the corner that do not appear in the slicer.
Did anyone have this problem before ? What would be the solution ?

We have leveled build plate. The first level is ropey with gaps, instead of smooth with no gaps. We are about to do factory reset. Any other subjections? Thanks.

This time i made a making video of a Antibacterial Facemask to protect yourself from CORONA Virus.The model was created by Ezteban.I am hereby clearing everyone that wearing the mask will not protect you from the virus clearly ,but then they are a preventive source of help for everyone as prevention is better than cure.This mask has not been medically certified however we are sharing this video as a means to find preventive measures to fight the CORONA Virus.
