It's been a while since I used text tracking in VP16, and using the text box is definitely not intuitive because it cannot be previewed in position. Once overcoming that limitation, it does work well though, really, it could be so much better.
I notice, Grazie, that the X and Y offsets in your first screen shot are both at zero. These do need to be adjusted to get the text into your desired position. Several times, I even needed to add spaces in front of the text in the text box to help get the text positioned to where I needed it. But there's no preview, so right now its very much trial and error.
I hope that I have read your issue correctly.
