VituixCAD issue with enclosure design

Hello and thanks for this great piece of software. However, I am having a couple of issues with the enclosure designer.
1. When I add a driver, enter all of the specs that I have and then click on the button to the left of the "Calculate T/S" button, a popup tells me most of those entries are missing!
2. In the driver configuration drop down, whether I enter 1 or 2 drivers, the box measurement results are the same although the graphs do change.
Could someone please tell me what is wrong.
Thanks
Peter
 
1. If entering drvier data from datasheet, just enter the data and "OK" to save. Calculate T/S is for T/S calculation from measured impedance. T/s calculation will not provide driver size, power rating, xmax, so those need to be entered manually. Unknown values leave as zero.
2. Check "auto-align" check in align tab. If checked, you should see enclosure volume double when selecting 2 drivers.
