You can fix this by doing the following steps on each visualization it will take about 1 min or less each.
In short there is a setting wrong in several of the Visualizations.

(NOTE: You should also do the 4 bar charts at the bottom as well, there is a bit of a odd behavior in one but that is a different nit / issue )
Edit the visualization
In the Visualization select the Panel Options and Drop The Last Bucket Save and Return
Now the metrics should be there and correct This just shows the first two I did
