Missing labels for REST and WS tasks in Designer

Description of problem:
If I create new process in Designer then I cannot find labels for REST and WS in Object Library. See the attached screenshot.

If I drag&drop such task on Canvas then the task contains a right label and right properties.

Version-Release number of selected component (if applicable):
6.0.2 ER1 BPMS

Steps to Reproduce:
1. create new process (default project - "project1")
2. Open section "Service tasks" in Object Library

Actual results:
see the screen shot. Labels for REST and WS are missing. The user cannot guess which item is REST and which item is WS. This is a regression.

Expected results:
Items for REST and WS contains right labels.
