I have 2 presentation and required clone slides from one to another one both presentation have 3 slides.
Step to reproduce error:

  1. Open first presentation
  2. Open second presentation and delete slide #2
  3. try to copy all existing slides from secon presentation to first presentation between slides #2 and #3

Note: InsertClone works fine if from second presentation don’t delete slide

Examples of presentations you can see presentations for first presentation use file “Cassandra Group 3.pptx”, for second presentation use file “Cassandra UK local 3.pptx”
