Impress File Template Gets Messed Up After Closing It

I’ve chosen a template for my Impress presentation file but after I do anything to the file:
1- Close it and reopen it again.
2. Copy it.
3. Save it as another format (PPSX, PPTX, …etc).
4. When I email it or upload it to someone.
The template design is changed totally. How can I fix that?
You can see below how the template looks like before and after the problem.

Exactly same problem here with this particular template! I wish that I’d know where template images are stored so that I could have imported them again, but could not find location of template files.

Best regards
