When using citations only to the text body, numbering is perfect. As soon as I cite to a text box in document, the citation reverts to 1 and others move up to 2 etc., regardless.
Experiment done in order:
cite to text body at beginning
then cite to text box 1
then cite to text body later
then cite to text box 2
Of course, it should be: , , , 
It actually came out in this order: , , , 
When the text box is cited, it takes an earlier number.
