In certain cases, duplicated articulations will show stacked on top of each other on a single note in Finale v26. In previous versions of Finale these articulations would have been overlapping each over and the duplicates would not have been visible. The auto-stacking feature in v26 will now cause these to stack above one another in a vertical row.
This issue has been found to be caused by files created in previous versions of Finale where the Implode/Explode Utility has been used to create a staff. This may also happen with documents that were created using SmartScore and then imported into Finale as a MusicXML document. There could also potentially be other causes for the issue, as well.
