My numbers in the PDF's are changing to boxes with X's in them.
I have a credit card statement and I am uploading all of the receipts associated with the statement. I am trying to write next to each charge which page number the receipt is on. I right click on the PDF and press "Add Text" and then write, for example, Page #1-2 next to the charge. Then, randomly, the numbers change (in this example the #1 and #2) to a box with an X in them. It's very time consuming going back and changing these from boxes to numbers just for all of them to change back to boxes with X's in them. Any ideas how to fix this?
