I have looked at your examples (thanks) and I don’t understand where the issue is.
When I re-generate your document (the ‘Short template..) one, I see a caption under the diagram, as expected.
What are you expecting?
Note: the ‘Preview’ tree view in eaDocX is designed to give you and idea of what your document will probably look like. It will not be 100% the same as the final document, because all kinds of information are left out from the tree view, so that it’s easy to understand. It’s mostly there to see where you have excluded items, and as way to see the overall document structure.
Please cn you provide a simple document which shows the problem (your ZIP file has 3) which show where the problem is.
