After using the Document Inspector, think-cell elements are corrupted

Problem

After using the Document Inspector of Microsoft Office some think-cell elements lost their think-cell functionality. The Document Inspector can be started in PowerPoint by clicking on File > Info > Check for Issues > Inspect Document

Using the Invisible On-Slide Content option of the Document Inspector removes some data relevant to think-cell. Afterwards, the think-cell functionality cannot be restored.

Solution

When using the Microsoft Office Document Inspector do NOT tick the option Invisible On-Slide Content.
