slides

Whenever am trying to delete slides of a simple PPT , it is possible. But am
working on a program where i have to use the previous layouts to create new
slides dynamically for more data.
Now when i try to delete a slide, it starts throwing error on that layout part
of code irrespective of the slide i want to delete.
The error is as shown
Exception in thread "main"
org.apache.poi.openxml4j.exceptions.PartAlreadyExistsException: A part with the
name '/ppt/slides/slide22.xml' already exists : Packages shall not contain
equivalent part names and package implementers shall neither create nor
recognize packages with equivalent part names. [M1.12]

org.apache.poi.xslf.usermodel.XMLSlideShow.createSlide(XMLSlideShow.java:206)
at Table.main(Table.java:9)
And my code is:
XMLSlideShow ppt = new XMLSlideShow(new FileInputStream("Template.pptx"));
XSLFSlide[] slide = ppt.getSlides();
ppt.removeSlide(11);
XSLFTable tbl = slide[1].createTable();
tbl.setAnchor(new Rectangle2D.Double(30, 100, 600, 800));
XSLFSlideMaster master = ppt.getSlideMasters()[0];
XSLFSlideLayout layout1 = master.getLayout(SlideLayout.TITLE_ONLY);
XSLFSlide slide1 = ppt.createSlide(layout1) ;
String str1 = slide[1].getTitle();
XSLFTextShape[] pht = slide1.getPlaceholders();
Thank you.
