Description:
A simple converted pptx presentation shows well in PowerPoint. However, when trying to change some bullet levels, things are messed up. This does not arise with a converted ppt presentation.

Steps to Reproduce:
1. Open the attached text.odp (simple presentation with some bullets of different levels)

2. Convert the presentation to pptx and ppt format

3. Open test.pptx

3a. Position the cursor at the end of "Text 1" and press Enter, then Tab to add a new lower bullet level: the cursor becomes tiny and the font size becomes very small. Pressing Tab several times doesn't do anything (no new bullet level added)

3b. Do the same at the end of "Text 3" or "Text 4" or "Text 5": the new bullet and text have the correct size but Tab doesn't do anything (no new bullet level added)

4. Open test.ppt and do the same as in points a and b. New bullet levels with correct size are created as expected

Note that ppt format has many issues with graphics formats conversion, so sticking with this format is not a viable solution.
