Hi there, I have two different PPTX files. One PPTX has only a single slide assume it to be `portfolioSlide` while the other has more than 5 slides let's assume `yourBigIdeaSlide`. I try to import content from `portfolioSlide` into the `yourBigIdeaSlide` and write output to "merged.pptx". If I open `merged.pptx` it fails to open saying it cannot be imported. Here is my repo to reproduce the bug: https://github.com/amustaque97/apache-poi In repo, we have all the source code and PPTX. How to run the project? Java 'com.example.abc.Main' Expected Output: Dev should be able to open the file and see the existing slides with the new slide imported from the other slide. Actual Behaviour: Not able to open the file. I tested for all the versions from 5.2.1 to 5.2.5 it is not working.
