Wrong Slide Chart Image when Exporting from a PowerPoint Presentation in Java

right now we are using java aspose-slides 22.9 and trying to parse uploaded pptx file(Charts2.pptx) and export slides to images. Slide has two charts which are not parsed correctly. Problems are shown ir red color.

Example of result image charts2_after.png

Image created:

slide.getThumbnail(new Dimension(IMAGE_WIDTH, height));

Can you take a look why this is happening and how we could fix that?

P. s. I have added IWarningCallback and no fonts are missing in this slide.
