Report Builder - bug using hidden parameter for objects with Font Size less than 8pt

Cheers bradsy,  thanks for the test and reply.

Not sure about product naming but are not 'Power BI Report Builder' and 'Microsoft Report Builder'  one and the same!?  I gather by 'Power BI Report Builder' you mean 'Power BI Desktop'!?  I suppose m$ marketing will add 'paginated' in there sometime to help distinguish between the two :}

I am using 'Power BI Report Builder' (paginated) as stated on the header line of the tool and the updates pop up below.  

Testing. 

1) being composite textbox, the first Branch line are hardcoded font size values and the second Branch line are hidden parameters

2) header panel testing,  first line hard coded and second hidden parameter values

3) body panel testing,  first line hard coded and second hidden parameter values

Running...

'This bag os no a work mate!'

I tripple checked to make sure the default value relate to each parameter and each test field matches the test description ...

Note for the Body panel test I used the same assignements as per the header test. eg  =Parameters!ParameterDisplay_FontSize7.Value

All hidden parameters are of Data Type Text which is the default.
