Adding a second subreport overwrites the first subreport file (4329711)

When adding a second subreport in the TDA Report Designer, the SQL script of the first subreport is over-written by the SQL script in the second subreport.
(The first subreport file was automatically named "DetailBand1" and when trying to put a second subreport into the report the name unfortunately stays "DetailBand1" and contains the properties of the first subreport. If changing the properties, the properties of the first subreport are overwritten.)

Both subreports are located in the same detailBand and there is no context menu option to create multiple detailBands.

WORKAROUND:
None

STATUS:
Waiting for a fix to be released in a future version of Toad for Data Analysts.
