Focus gaining is broken.

[(PSN)omgthat132]

So i started to get into focus farming, got an eidolons lens slapped it on volt and went to sanctuary onslaught so, i play it a few round and i get increacing ammount of focus each round which is great! the focus time runs out and i have about like 30k earned it says, then.... i check the menu and its says like 10k earned so thats completely off and its not an UI bug either because when i come back out of the mission and go to my zenurik tree it says the same thing.. i even tried login out maybe it was some sort server bug where it didnt count them or something but no. So everytime i gain focus i basically lose half of it out of nowhere which is frustrasting is this a known bug or do i just dont know something?
