Not sure on map name

[Looter]

I would see them having lost their way to you in the first picture since you jumped down to a place unentirely mapped by the Ai mesh and them having no idea on where to go. If they were on the ground already they would have run straight for the wall, but since they were above and you jumped somewhere they have no mesh to and are so close to them they just stand there trying to take the shortest path to you despite being unable to reach you. As for the second picture, Ai stupidity like alpha said, not sure on a fix for that since the Ai mesh is the only way we can guide bots.
