Created attachment 38018 [details] Test document Paragraph and text runs properties don't fetch from the master slide. https://github.com/apache/poi/blob/REL_5_0_0/src/ooxml/java/org/apache/poi/xslf/model/ParagraphPropertyFetcher.java#L75 In this case, receives default master properties. See the attached document and pay attention to the text alignment of copyright in the footer.
Thanks for reporting the issue. POI is a volunteer project and not many of the existing community are active on pptx support. Would it be possible that you or your team could contribute a patch?
Thank you for the test file. Fixed via r1894140
