The values of contributor attribute which depends on other attribute aren't displayed correctly in Web UI

I am using RTC 3.0.1.3 and customizing my Project Area and found that the values of contributor attribute which depends on other attribute aren't displayed correctly in Web UI.

steps I used:
- SCRUM PA
- TEAM 1 - member Eric Jodet
- TEAM 2 - member User 2
- category 1 associated with TEAM 1
- category 2 associated with TEAM 2
- create a new attribute - type = contributor - depends on "Filed Against"
- add presentation to defect type

use case
- create a new defect
- set filed against : category 1
A - expected: custom contributor combo is populated with member or TEAM 1 - Eric Jodet
- set filed against : category 2
B - expected: custom contributor combo is populated with member or TEAM 2 - User 2

issue:
A - works fines with Eclipse UI
B - does not work with WebUI

is this a defect?
