2019 FDK, FV_SaveFmtBinary140 problem, save file as previous version

Hi

In our custom application we have a function to save files in older versions formats using the FDK.

I am using the latest FDK to save a file from v2019 to v2017. I use the "FV_SaveFmtBinary140" definition to save the file in binary format. Run the process but file cannot be opened with v2017.

If I use the same function with "FV_SaveFmtBinary130" instead, it saves the files into v2015 format correctly. We have done this since v11 in the same way between consecutive versions.

Am I missing anything? Has something else changed in the latest FDK or something missing?

Thanks.
