In a Numeric Entry Field (haven’t tested with other input-type elements, I set the align property to center and the text centers within the Numeric Entry as expected, but I still see an error in the Property Editor saying align: not in enumeration [right, left] and the dropdown selector for the align property only allows me to select right or left.
As the title suggests, typing "center" in the align field of a numeric entry component in perspective renders the numbers correctly in the center, but an error/warning is shown in the props:
The error text is:
align: does not have a value in the enumeration [right,left]

Correctly renders anyway:

Edit: This is on 8.0.7
