Grouped visuals, introduced in the August 2019 update, appear to all align to the top left corner of the page when exported to PDF or PowerPoint. Below is a screen shot of the PowerBI Desktop file then the published report exported to both PDF and PPTX. I have also tested this in both Chrome and Edge with the same results.
The good view in PowerBI desktop:

The bad view after export:

Has anyone else run into this behavior? I really like the grouped items for working with bookmarks so I am hoping this get fixed soon.
