A few months ago I splitted some lines in a shapefile with official roads because they are not accessible anymore. Now I loaded that file again into my project and the splitlines appears. Because I didn't made a legend yet, they show up. (see the picture below)
edited: I first selected the layer and turned on the toggle editing. Then I activated split features . I drew a line across the point where the road had to be split. After doing all the splitting, I turned off the toggle editing mode.
Is it normal that splitlines are saved in the attributetable? Can this be avoided? Because it is messing up my data.
