Help me! I cannot change text alignment

Hello all
I feel like I’ll probably embarrass myself, but here it goes:
I’ve opened a project from Scrivener 1.9 in the new Scrivener 3 beta. Everything seems to work fine, with the exception of… alignment. All the alignment options are greyed out, and I can’t for the life of me figure out why.
Thanks you!

Just a random idea, but did you click on the text you want to edit?
As long as the focus is on Outliner or Binder (you’ve JUST clicked on the document title), the options to format text would be disabled.
