Hi Armand,
There are 2 open defects raised against PAW 73 in regards to tab rename behaviour:
PH44195 WORKSPACE BOOK TAB TITLE IS NOT SAVED WHEN BOOK IS SAVED
PH44423 WORKSPACE ACTION BUTTON NAVIGATION SELECTION DOES NOT SHOW UPDATED TAB RENAMES
For PH44195 there are 2 workarounds:
1. Hit Enter instead of clicking away after entering the title for the tab.
2. Open Dashboard properties > Tabs > Individual Tab Styling > Click on the Tab and update the Title. Save the book.
Hope this helps
