Hi Minh,
Thank you for your prompt response. I am using the USA version on Catalina. I did not add any stories to the model. However, it is a large, older project with hotlinks, generated back in 2016 (AC20?) and migrated since then. Given its age, I opened a few other projects created in prior AC versions. I found the 'TabBar' display appears to occur in projects created prior to AC23. (The two projects I created in AC23 and one I created this morning in AC24 display the correct menu choices.)
