Known Issue: Custom Transformer Version Resetting to Version 1

Issue

When opening a custom transformer .fmx in FME Workbench, and editing the Transformer Parameters, the Version resets to 1 and needs to be manually corrected. 

Workaround

When editing or creating a new version of a .fmx custom transformer, prior to saving, open the Transformer Parameters > General > Version. Double-click on Version and manually type in the desired version. Correcting the version should be the last step prior to saving as editing any other parameters will reset the version back to 1. 

If correcting an already incorrect version, when opening the .fmx in FME Workbench, when prompted to Create a New Version or Edit an Existing Version, select the incorrect version, which will usually be the version at the top of the drop-down. 

If the incorrect version has already been uploaded to FME Hub, download the transformer, then update the transformer version as listed above, then re-upload the transformer to FME Hub.
