Inconsistent / Broken Terminology

Within Marketing, Business and Project Lines, the customize terminology setting is broken and creates an inconsistent user experience that confuses users.

Within the 'Customize Terminology' setting (Settings > Product Line > Terminology), if you make changes to the release/schedule field, it's not reflected in the navigation bar at the top but is reflected in the buttons and other areas of the body confusing users by:

• why did a settings change not have the intended impact

• why are there different terminologies across a single view eg gantt view
