Anyone else having problem with Filtering??

Anyone else having problem with Filtering??

I am wondering if anyone else has this problem with filters.  I have been on the phone with Ruben all week and apparently their developers are working on it,  but I am not seeing any progress.

~ I have a form in which the user enters staff position and names (POSITION TYPE).
~ My main form allows the user to select different people of different positions to assign to a task(TASK).  The fields are five lookup fields from the Position type form.
~ In the view of the Task form, under filter, it is combining all of the names entered on the Position Type form for each position.
Example:
---POSITION TYPE
   Position A
       Person A-1, Persion A-2, Person A-3
   Position B
       Person B-1, Persion B-2, Person B-3
   Position C
       Person C-1, Persion C-2, Person C-3
---TASK
   Under the filter at the top of the view,  it shows
Position A
        Person A-1, 
Persion A-2, 
Person A-3
Person B-1, 
Persion B-2, 
Person B-3
   Person C-1, 
Persion C-2, 
Person C-3
Position B
        Person A-1, 
Persion A-2, 
Person A-3
Person B-1, 
Persion B-2, 
Person B-3
    Person C-1, 
Persion C-2, 
Person C-3
Position C
        Person A-1, 
Persion A-2, 
Person A-3
Person B-1, 
Persion B-2, 
Person B-3
    Person C-1, 
Persion C-2, 
Person C-3

Like I said, Zoho developers are twiddling their thumbs or something, so I'm wondering if anyone else has this problem.  I need to take this app live on Monday and this filtering thing is one of the mainly utilized features that I need.

Thank you.
