@josephcampos-gap Thanks for the report! I tried to reproduce this with two sample flowcharts (LR and TD) and graph in Presentation Mode but couldn't replicate the issue on my end.

I've attached markdown samples I've tested.

And here are the screenshots:

Could you share the Mermaid source of the flowchart that wasn't displaying correctly? It's possible the issue is related to the diagram's complexity or a specific syntax.

If your diagram contains sensitive information, feel free to replace it with dummy text - just keep the overall structure intact so I can reproduce the issue.
