Well, that depends upon the owner of the objects. Since you transported the objects, the owner of the objects could be the Transport / Import user.
Can you please also check if the underlying tables for the attribute views are active.
It is also possible that if the objects collected on the export were inactivated due to the change in the underlying table changes, then it might result in the situation of having active and inactive objects in the repository.
I hope you are working in the Modeler perspective. As per the documentation:
If your development is based on Repository / workspace, then you should be able to see the object in your default workspace.
I'd suggest you to refer to the section 6.7 Activating objects in HANA Modeling Guide for the different scenarios for activation. It may help you under the issue in a better way.
