MetaQueries not displaying data with "--Mixed--" datasource selected #115

Good morning,

I am trying to make a simple aritmetic operation with two variables in MetaQueries (A['variable 1']/B['variable 2']). Well the issue I think it comes because each of the variables comes from a different datasource - Therefore the data source selected is "--Mixed--":

Here it is the definition of both variables:

Query A - ALIAS BY "variable 1" Description: absolute counter for the parts produced over the lifecycle of the machine // with the transformation "difference" I extract relative values per day. Datasource 1: "ConditionMonitoring" image

Query B - ALIAS BY "variable 2" Description: absolute counter for the energy consumption (electricity) over the lifecycle of the machine // with the transformation "difference" I extract relative values per day. Datasource 2: "EnergyConsumption" image

MetaQueries query: image

Note: each variable is displayed in the right way however I receive nothing when I hide all variables except the calculated one:

Furthermore, I have tried to make a simpler calculation (A['variable 1']*2) with the same result.

Has anyone faced this issue? Is there anything wrong in the definition?

Thanks a lot in advance!

Best Regards Adrián
