question about usage tracks

[circe801]

i regularly scan for and remove usage tracks. in my last installation of windows 10, there were 2 results that kept coming back no matter how many times i tried to remove them. i never saw them again after my new install--until today. i will attach a screenshot. what bugs me is why did they reappear all of a sudden, and what do they mean--especially the (is not) after the entries? i can't help but think this is something suspect and/or sinister. please help to put my mind at ease... thanks!!
