After upgrading to R23-1 it might happen that configured workflows have "less steps" as expected (e.g. 7 steps instead of 21). While the WebUI shows the first steps only, the XML output via API is fine and every step is still configured.
Tufin support has confirmed this behavior as a bug that will be corrected in R23-2 PGA2.00 which will be published on December, 20th. Until then, it's recommended to use the zoom function of the browser.
