Missing Text, Cells, and Rows in a Table when Using GetThumbnail Method in C#

I use .NET Library Aspose.Slides 24.2.0

I have a presentation with slides, only 1 shape inside table, with columns and cells with text inside.
But when i generate a thumbnail via “slide.GetThumbnail()” my generated image contains a table with no rows, cells and columns, it’s just empty. Could you please help me to figure out?

In some other presentations with the same shape it works properly, so there is a chance some property settings are missing. please help (I would attach pptx so you can investigate it but your forum doesn’t allow to do it)
