Two issues occurred in the Portfolio Timeline Gantt visual:

▪Duplicate programs – When a project had the same name as an existing program, the program was displayed twice in the Gantt view.

▪Filters not applied correctly – The Project and Project Manager slicers did not filter the Gantt view as expected. Although a previous fix had resolved duplicated portfolios in the Scheduler, a separate issue in the grouping logic of Planner projects persisted.

Expected Behavior:

The Gantt view should correctly group programs—without creating duplicates when equally named projects exist—and it should fully respect Project and PM slicer filters.

Bug Fix:

The configuration of the custom Deneb Gantt visual for Portfolio Timeline and Project Timeline has been updated. This resolves both the duplicate program grouping and the incorrect filtering behavior, ensuring that Planner project grouping and slicer interactions now work as intended.
