Shape disappears when converting ODP to PPTX

We are using “slides-19.10-jdk16.jar”.
The attached ODP file has an oval shape in it, however when we convert it to PPTX the shape vanishes.

Using the following code:
com.aspose.slides.Presentation presentation = new com.aspose.slides.Presentation(inputPath);
presentation.save(outputPath, com.aspose.slides.SaveFormat.Pptx);

@simon.wiseman,

I have worked with the presentation file shared. An issue with ID SLIDESJAVA-37854 has been created in our issue tracking system to further investigate and resolve the issue. This thread has been linked with the issue so that you may be notified once the issue will be fixed.

The issues you have found earlier (filed as SLIDESJAVA-37854) have been fixed in this update.
