Bar chart missing in NPM 2020.2.5


After upgrading to Orion 2020.2.5, Bar chart for TOP XX CPU, Memory, volumes is missing. Its just showing a number instead of bar chart.

Bar chart is only visible on template named "Nodes with high CPU/Memory/Volumes" that has predefined global thresholds.

Please let me know if there's any way to bring back bar chart for TOP XX .
