Gantt Dashboard shows ghost dates (2016) from 10 connected boards - NOTHING works

Hi Community,

URGENT PROBLEM: My Gantt dashboard shows impossible dates like 2016 that DO NOT EXIST in ANY of my 10 connected boards.

What I've tried (15+ fixes):

  • ✅ Filters: Status "Not started/In progress" + Timeline >2026 ✓

  • ✅ Visual settings: Hide completed ON, Critical path OFF, Baselines NONE ✓

  • ✅ Disconnect/reconnect boards 1-by-1 (no change) ✓

  • ✅ Delete + recreate widget (new dashboard) ✓

  • ✅ Incognito mode + Ctrl+Shift+R cache clear ✓

  • ✅ Delete ALL Gantt views + recreate ✓

Key facts:

Screenshot attached: Dashboard Gantt (left) vs Table (right) - same boards, different dates.

Question: Is this a known bug with multi-board Gantt dashboards? What creates ghost dates not in source data?

Need: Working Gantt OR official workaround for 10-project timeline.

This feature worked in the past, is anything new that is not working?

Thanks!
