Your document's first endnote lacks the endnote reference in the endnote area. Someone as deleted it and replaced it with a typed '1'. That typed number will not auto-update. You can fix that by:
• cutting the endnote content from the endnote area;
• deleting the endnote reference in the document body;
• inserting a new endnote there; then
• pasting the cut content back into the recreated endnote 1.

Your inconsistent endnote formatting is because someone has been messing with the endnotes. When Word creates them, it applies a consistent format to them.

PS: Your document needs a serious dose of spell-checking.
