Confluence Create from Template macro with User created Space template did not work after Space import.

Steps to reproduce

1. Create a new Space
2. Create a User Created Template from Space > Space tools > Template > Create New Template
3. Create a Test page in the space and insert the Create from template macro and choose template created in step 2.
4. Create a page by clicking on the "Create From Template" button - success
5. Export the space to XML.
6. Delete the Space.
7. Import the Space into the same Confluence version.
8. Rerun Content Index
9. Create a page by clicking on the "Create From Template" button.

Expected result
A page with the user created template will be created.

Actual Result
The create window loading blank.

Workaround
Edit the Create From Template macro in the test page (step 3) and re-selecting the template resolves the issue.

Notes
The bug only persist when the User created template is created through Space > Space tools > Template > Create New Template. This means that the bug didn't exist if the user created template is created from General Configuration > Global Templates and Blueprints > Add Global Page Template.
