Used Visio 2019 Professional
There is an organization chart with about 200 shapes per sheet.
This OrgChart contains external data (currently quite a lot, but some of them are not used) and drawings related to the data.
Visio features are used: such as synchronous copies, and reports.
Sorry, but I can't provide a sample file.Problem Description
At some point, a certain glitch occurs: an error message appears when selecting shapes and running the OrgChart11 add-on.

At the same time:
- Shapes retain all custom properties (Shape Data);
- Shapes are no longer org chart shapes (they don't have parent master shapes);
- Figure data is no longer used as chart fields.
Possible causes of the problem- Launching the Report Generation add-on;
- A lot of custom properties.
Please share your experience on how to prevent such problems and / or even defeat them ?Original post in Russian language (read via Google translate Service)
