I can reproduce. Latest studio build, x64 windows pc. Noticed yesterday, I don’t know if it was there before too. I tried restarting and reinstalling studio too.
This has been happening since the 10th when I first saw it reported and I commented on it.
Link to the post from the 10th. Align Position properties not showing up
(I’m not the OP, I tried to put it in bug reports and make a new thread but it wouldn’t let me.)
Just a reassurance for anyone who runs into this: The properties have not been lost, and you can in fact still set them from scripts / the command bar just fine, this is only a display issue in the properties pane.
In the meantime it’s easiest to just use the command bar to print and set properties of AlignPositions as needed (if it’s not just set directly in code)
