Hello Lords of Word.
This problem takes some describing. I have a word template for a standard letter for my work. There is one of those built in envelopes that you get when you go MAILINGS ribbon > Envelopes > "Add to Document". So the template starts with the built-in envelope,
with its preset characteristics. There's a little invisible sort of table or cell for the Delivery address built-in. In that table/cell, I've put in two REF fields that refer to bookmarks for the name and address in the letter, which I'll describe next.
After the envelope page, follows the letter, and in the Letter I put a bookmark called Name and another called Address. Nested inside each bookmark is a formfield. So I hit F11, it jumps to the field inside the "name" bookmark, I fill it in. I hit F11 again,
it jumps to the next field, inside the "address" bookmark, and type 2, 3 or 4 lines for the address, hitting enter for a new paragraph between lines.
Final step: Ctrl, A selects the entire doc, I hit F9 to update the REF fields in the envelope, the info in the bookmarks flows into them and my envelope is automatically filled in. This has worked pretty well for years.
Something has started to go wrong, though I've made no changes to my templates. If my Address book mark has a two-line address it all works fine as below:

But if I have a 3-line address (quite common), the 2nd line relocates like this:

I can just move the 2nd line back into place, but this is extra steps, trips me up if I don't notice it, complicates me training my staff, and I think this might cause big problems with a mail-merge down the road. So I really need to fix it. Any way I can
make the REF fields in the Envelope behave themselves?
Thanks in advance.
