Bug Report: Dashboard devices removed when creating Contact Graph

I experienced a bug in dashboards that I wish to report.

It happens either when editing an existing EZ dashboard or creating a fresh blank EZ dashboard and proceeding to edit that.

I added a multi-sensor device, specifically, a door sensor with contact, acceleration, and a few other standard attributes. I edited the device and changed its Tile Type to Graph, and its Shows value to Contact. I left the other settings as they stood: Graph color, Background color, custom icon. Create a duplicate was unticked, and Apply to all was ticked. Then Save, refresh page to reload and begin seeing data. BUT at this point the dashboard appeared but completely blank, with all previously placed devices GONE.

I tried coming in again through the Dashboards menu, same blank dashboard. I tried editing the dashboard, and adding or removing some devices. No change. The dashboard seems completely blank and unusable at this point, and nothing I attempted to recover it worked.

Platform Version2.5.0.157

Hardware VersionC-8 Pro

Please advise, and please let me know if any further information would be helpful

Thanks and best regards,
