I have had the same problem on occasion.
It seems that drawings place on a master file do not updtate and do not show on the PDF (I always publish to PDF) but lines and text on the same master show up just fine.
I have also found that the same master used on susequent pages publishes to PDF just fine.
It seems to be the first time the titleblock drawing is published it hasn't updated in time but is fine for the rest of the pages in a merged multi-pgae PDF.
And it is only sometimes and did seem worse in version 12 but I have had reports of it since in later versions.
At least this is my experience.
The only solution I have found is to force the Masters to update by right clicking on the Masters folder in the Layouts section of the Project Map before you publish the PDF.
