Weird layer in cura

[janis12 0]

Hello, does anyone have idea what can couse that weird path? Layer before this one is crystal clear it is the layer before it model ends at some height and it prints 1 mm high. 
So my question is why it first prints some marks on finally solid surfes but it waste time to make so complicated path.
1 picture is with orange whole surfece is solid 
2 picture with only orange shuriken symbol still it is solid 
3 picture is with next layer and only orange and red lines are printed
