Gridpos being overwritten

I’m using Grafana v 9.0.5 on a Linux system.
I have a dashboard with 3 bar charts arranged vertically and three tables arranged vertically to the right of the bar charts. I want each table to line up horizontally with a bar chart. I tried modifying the gridPos y parameter in the json of the table panel to move the tables down to align with the bar charts, but when I hit apply, it has no effect and when I inspect the json, the value I put in has been overwritten.
Here is the link to the dashboard.
