Could you please provide us with a diagram that allows us to reproduce the issue? Also, just to make yourself understood better, consider including a screenshot or capture to establish the context.

Never mind my previous comment. I was able to revert the change on your diagram to come up with the original that allows me to reproduce what you’ve reported. Cf. screencapture attached :arrow_up:.

Thanks for reporting this issue.
