BUG: drop down parameter lists vanish from DPC load data or schedule panel

If this occurs, it means there are NULL values in the config_rqp table. To solve, either remove NULLS or apply these patches:

• p_UI_LOADPANEL_v1.1.15.sql
• p_UI_SCHEDULEPANEL_v1.2.1.sql

The following patch handles the NULL's more effectively. These patches are available by default in the 107 pack and above.

NULL values in the config_rqp table may also cause this issue as well:
