Set analysis Script is shown as we hover over the filter in qlik sense.

When using a calculated dimension in Qlik Sense and hover over it in the dashboard we could see entire script displayed. And, ideally using calculated dimension is not the right practice when using data modeling as it would create a virtual data model and the engine service would not know what to display on the front end and thus displays the expression applied to the dimension.

 

In ideal scenarios, we don't set any expressions on a dimension and rather use dimension and to filter that out we use measures. However, if we would like to filter through values using dimensions (that is filter through dimension values by applying selections on dimensions), then we may add this expression or calculated dimension inside the script in data load editor within a load statement as below, 

LOAD
street,
city,
zip,
state,
beds,
baths,
sq__ft,
"type",
if(not match(type,'Condo'),type) as mydimension,
sale_date,
price,
latitude,
longitude
FROM [lib://AttachedFiles/Test_data.csv]
(txt, codepage is 28591, embedded labels, delimiter is ',', msq);

then add a filter pane from charts and add this dimension in the filter pane to work as per your expectations.

I can confirm by looking at the sample app that is 100 percent working as designed and there is no product defect. Infact, I suggest you to touchbase with your account team for some educational services to know how to work with Qlik Sense.
