I just updated some gateways (3 total) to version 8.1.37 (from 8.1.26) and now some reports don't show their correct data in the PDF viewer in Vision. The actual PDF documents have the correct data with no problem but just when viewed from vision it shows null values as squares.
Within Vision, I use a file viewer and a PDF viewer to display reports from a singular directory. All reports are generated based on tag change scripts and saved to a dynamic file structure. Users then select reports for review or printing in the file view/ pdf viewer combo. It's ugly but we have been doing this since 7.8.1. The data missing in Vision is based on an SQL joined query but nothing too interesting.
actual pdf file (in edge):
any advice or a better way to do this? I can provide additional information if required.
