Steps to reproduce :
Log with GardenAdmin and goto Client window.
Untick 'Multi lingual document'
Log off and relogin using any language but English
Launch a report
Goto Customize Format and change an item printname (the item has to be related to a translated element and maked as centrally maintained)
Note that your change has been considered.
Now, log with System and launch a SynchronizeTerminology process.
Log off and return to GardenWorld.
Launch the same report and you will see that your printname has not been updated (main or trl table), while it was marked as centrally maintained !
WDYT ? Is this a bug or a feature ?
