Date in table only is displayed after select - firstSortedValue

[#1]

Hallo!

I'm wondering about my firstSortedValue function...

In my Project i have a table chart with following Dimensions and Expressions:

Dimension:

     - SERIAL_NO

Expressions:

     - Max({<Date={'<=$(currentDate)'}>}Value_Amount)              

               -> Seems to work fine

     - Date(FirstSortedValue(Date,-Aggr(Max({<Date={'<=$(currentDate)'}>}Value_Amount),Value_Amount)))

               -> for some values directly shown, for others i have to select a SERIAL_NO

     - Avg({<Date={'<=$(currentDate)'}>}Value_Amount)              

               -> Seems to work also fine

To make this more clear, some screenshots.

Sry for censored fields, but i rly cant share the project^^

Without Selection, the table chart look like NoSelect.png and after select like selected.png...

The funny is, the Date is correct^^ But why only after select?

Thanks for any help:)
