Just posting this unusual, circumstantial constraint on editing interactive schedules should anyone have the same issue : If the initial work session window is on an extended display and the Row Height setting is too low/tight, the active field edit icon for list values (e.g., Classifications, Property Option Sets, etc.) may be invisible, thus appearing locked and preventing selection edits.
Background/Detail:
I have several schedules, all of which utilize the same dedicated LC (All On and Unlocked), RS (Show All), and MVO (All Detail). All data constraints are in the Schedule Criteria. This setup has greatly simplified my editing sessions, except for a few schedules where I was not able to edit various fields. On one of them, I decided to increase the row height with 10pt text from .2in to .3in. The edit icon was immediately visible. Interestingly, if I drag the session window to my main, albeit smaller MacBook Pro display, sometimes the edit icon will show, sometimes not. While I have not tested the various scenarios extensively, it appears there is a relationship here to be mindful of should you experience this behavior.
