Incorrect shape names in the Style definition for flowchart shapes

[Eokusu3478]

Description
There appears to be a naming mismatch for certain flowchart shapes in the Style definition. Specifically, the names for the **summing j

unction** shape and the or shape seem to be reversed in shape=mxgraph.flowchart. Although the correct shape names are shown in the sidebar, the internal style naming appears to point to the opposite shapes.

Steps to Reproduce

1. Open the online version of draw.io.
2. Insert or edit the summing junction shape and the or shape in the flowchart library.
3. Check the corresponding Style definition using shape=mxgraph.flowchart.
4. Notice that the shape names in the style appear to be reversed, even though the sidebar shows the correct names.

Expected Behavior
The style definition in shape=mxgraph.flowchart should correctly map to the actual summing function shape and or shape, so AI or other style-based generation methods can produce the correct shapes.

Actual Behavior
When I try to use AI to generate the correct summing function shape and or shape, the two shapes are generated as each other’s opposite, because the style naming does not point to the correct actual shape.

Environment

• Version: v29.7.1
• Platform: Online version

👋 Thank you for opening this issue!

Summary: The user reports that the internal style names for the flowchart 'summing junction' and 'or' shapes appear to be swapped — the style shape=mxgraph.flowchart.sumjunct renders the 'or' shape and vice versa — causing incorrect shapes when generated programmatically or via AI using the style definitions.

📝 Additional Information Needed

To help us investigate this more effectively, could you please provide:

• browser: The specific browser used is not mentioned, though this is likely irrelevant for a shape definition bug.

We also have some questions:

• Can you confirm the exact style strings you see for each shape? For example, does the 'summing junction' shape in the sidebar produce a style like shape=mxgraph.flowchart.or and vice versa?
• Have you verified this in the stencil XML definition file (e.g., the flowchart stencil XML) to confirm the mismatch is at the stencil/shape definition level rather than just a sidebar label issue?
