Why is the fertile window in my finished cycle light with a dashed border?

kegg’s algorithm needs consistent readings throughout the cycle to place the fertile window confirmation in completed cycles.  If there are not enough readings in a cycle, kegg will approximate the fertile window placement.  

In the example shown, the user has missed readings throughout the cycle and has missed readings during her fertile window prediction.  kegg does not have enough information and is placing it’s best approximation based on the user’s cycle history.”
