That is strange.
However if you can't find another solution you can go likr this:
To make a profile current before starting the program
- On the Windows desktop, right-click the program icon. Click Properties.
- In the AutoCAD Properties dialog box, Shortcut tab, under Target, enter /p currentprofile after the current target directory. For example, to make the profile User12 current, enter the following in Target: "c:\Program Files\<current release name>\acad.exe"/p user12
- Click OK. The profile name you enter is the current profile each time you start the program.
