One of the customer is facing an issue where in IFS Developer Studio 18 in the created project the components below 'person' are not visible as shown in the below image. 

After updating the Target Version to 24R1 GA, components up to 'wrksch' are visible but still cannot see the component 'wscope'.

Product Version: 24.1.0

Developer Studio Version: IFS Developer Studio 18 (Build 24.1.0142 2024-05-31)

I have checked in IFS Developer Studio 18 (Build 24.1.0142 2024-05-31) and (Build 24.1.0169 2024-06-24) and couldn't recreate this issue since all the components until 'wscope' were visible as shown in the below image.

Is there any explanation for the behavior?
