We should see if works with only the first frame, and if it does only put it there. Else were could be repeating this string a lot if there are many items in the response.

What is this feature?
Updates reduce command expression to apply modes
DropandReplaceto mathexp.Number.Also, it changes when the warning is returned. If mapping mode is not Strict, the warning will not be added.
Why do we need this feature?
Initially, the expression applied this mode to mathexp.Series (i.e. time-series). However, from user's perspective, the format of data may not be clear and the expression behavior looks different.
Who is this feature for?
Alerting users that query data sources that return vectors and want to drop\map non-numeric values.
Which issue(s) does this PR fix?:
Fixes #74645
