Object highlight (Actor has tag)

I am having a problem which I cannot figure out. I have attached a picture of the blueprint. This issue I am having is that line trace works OK when looking at an object and that line trace is interupted with nothing when looking away. However if I stack 2 of the same objects that have the same tag and look at the top one first and then look at the bottom one. The object is still highlight even when I look at something else. Help would be greatly appreciated.
