AI Perception sight stimulus fires twice when player enters cone of sight perception, is this a bug?

AI Perception sight stimulus fires twice when player enters cone of sight perception, once with valid stimulus location and once with very high and invalid vector values, is this a bug?

I have taken screenshots of the AI sight perception issue I have between my AI and Player.

Valid values, fired first.

Invalid values exist in the same event triggered on perception sense, where are these coming from?
