4.20 is having functionality to change the units in which the metrics are displayed, but the functionality is having an issue because it does not give any error or warning when a invalid unit is selected, For example when we run a query that is going to give value in Kb/MB  now when in the drop down we select Percentage or Seconds/MilliSeconds, it returns output by simply adding the suffix to the value Adidng screenshot in details

4.20

Easily reprpducible

    1.in 4.20 query any metrics 
    2. From the drop down select a unit that is unrelated to the actual value of the metrics , it still shows the output
    3.
    

Value displayed with incorrect unit

If the selected unit is not valid wrt metric it should give error

This is happening to all the type of query, so there needs to be a validation check for all the metrics that have a unit defined
