see attached screenshot. According to the end event analysis two instances have reached the end event. According to the gateway analysis one instance has taken the no path at the invoice approved? gateway and one instances has taken the yes path.
Compared to history data of the process in cockpit the end event analysis is correct.
Both instances have taken the yes path so the counter in the gateway analysis should display that.
One of the instances has executed the invoice approved? gateway twice (see attached cockpit screenshot).
