A CU that does not have a particular work function configured in Available Work functions is incorrectly shown in the CU tab when that work function is selected. In this example, the withoutinstall CU is shown, even though it does not have Install in its available work functions.
This is caused by having CUs directly under the Compatible Units category. Bug CLS-63786 has been logged for this issue.
The workaround is to place all CUs in a category. In this example, the 102350 CU directly under Compatible Units was moved to the Non-GIS category to resolve the issue. Note that the withoutinstall CU is no longer shown with the Install work function chosen.
