Rubert Client Orders

Am I the only one having this problem with Rubert Client orders where it calls for you to destroy certain parts before killing them not registering? I had it happen for two of his client orders. The client order where you have to destroy the middle head of the Vid Gilos before killing it and destroying the right foot of Gigur or Gunne Ginna-gam before killing him.

Not sure about Gigur, but I believe for the Vid Giros you need to kill 3 of them this way to complete the CO. For Gigur, do keep in mind that you are requested to break his right foot which is to your left if you are facing him. It is possible that you might have broken his left foot which is to your right.
