I tried recreating something similar to this, and I couldn't get the Cube View to do what yours is doing when I used the GetDataCell(ABS(CVR(Row1)). When I did this, both rows populated with the same value. I had to use GetDataCell(ABS(A#100)) for it to work, this may fix your issue.
When it comes to the Report/Excel options, it could possibly be due to your formatting for the Report and Excel versions. If that red is coming across, that is depicting the negative value instead of using () or a - sign. You could update this in the Cube View Properties Cell format, or in the ABS_Row1 cell format.
