Create Custom Date Fields for Baseline Bars

This workaround bypasses the rendering issue by using custom calculated fields instead of the default baseline dates for your Gantt chart bars.

This disappearing baseline bar issue is a known behavior in certain versions of Microsoft Project. It primarily occurs when a status date is applied and the option to round bars to whole days is cleared.

By mapping your baseline data to custom Start and Finish fields, you can force Microsoft Project to render the bars correctly.

Insert custom date fields

Open your Microsoft Project file and insert two new custom date columns into your project table, such as Start1 and Finish1.

Calculate baseline dates

Set the formulas for Start1 and Finish1 so they calculate and pull data directly from the default Baseline Start and Baseline Finish fields respectively.

Modify Gantt chart bar styles

Double-click the Gantt chart background or navigate to the Gantt Chart Format tab to open the Bar Styles dialog box. Create a new custom bar style for your baseline.

Apply the custom fields

Configure the new custom bar to use Start1 and Finish1 instead of the default baseline fields, then click OK to apply the changes to your chart.

Feedback to Microsoft: You can report this specific status date rendering bug directly to the Microsoft 365 feedback platform to help prioritize a future patch.
