Why some of a picture slide wasn't rebuilt

Only what can be read clearly becomes editable, so nothing is guessed.

The rebuild only turns into editable text, tables and charts what it can read clearly. On a blurry, low-resolution or very busy picture, words it can't read surely, and the tables, charts and text boxes that hold them, remain part of the picture, so nothing is guessed. For more editable content, upload the original PowerPoint or a sharp PDF export.
