@SimsNateia Hello! I checked this in my game as well and it is working as it should. I wanted to clarify some things and expand a bit what @crinrict said. The controls change depending on which way your sim is facing in profile and they'll change depending where you click when the sim is facing you.
- In left facing profile, clicking on the bridge of the nose and dragging to the left increases the nose curve and lowers the tip, dragging to the right decreases the nose curve and raises the tip. Clicking the tip then dragging to the left elongates the nose, dragging to the right shortens the nose, dragging up and down will respectively raise and lower the nose height.
- In right facing facing profile clicking on the bridge of the nose and dragging to the right increases the nose curve and lowers the tip, dragging to the left decreases the nose curve and raises the tip. Clicking the tip then dragging to the right elongates the nose, dragging to the left shortens the nose. Dragging the nose tip up or down still raises and lowers the height.
- While front facing, clicking on the left side of the nose and dragging left will widen the nose, dragging right will narrow. Clicking on the right side of the nose, dragging right will widen and dragging left will narrow. Clicking anywhere on the tip and dragging up or down will raise or lower the nose height.
If this is not how it is working for you, then it would be really helpful for you to share a video as crin mentioned earlier. I made a video using Xbox Game Bar for Windows. This sort of external game recorder shows the movements of the mouse in CAS. The game bar controls will open by pressing the Windows key plus G on the keyboard. Once you click the record button, just click into the game to manipulate it while the recording continues. For me, the record button panel appears on the right side of the screen during the recording for when I'm ready to end it. Here's a link to the video I made which shows how the nose slider controls are working for me as I described above.

It is possible to attach videos here but the player for AHQ isn't good. So it's better to use a file sharing site. You don't need a YouTube account or subscription to upload videos. I uploaded my video to YouTube using my Google account. You can also share videos in Google Drive like crin said. If you don't have anything Google related, then perhaps you could upload it to another file sharing site and then copy / paste the link. Hope this helps!
