Hi!
There is *.properties files in SD for translation purpose. But these entries are duplex (some of them are differs only in case):
sdp.change.changeId
sdp.change.changeid
sdp.admin.notificationrules.purchase
sdp.admin.notificationrules.purchase
sdp.admin.notificationrules.contract
sdp.admin.notificationrules.contract
sdp.header.Software
sdp.header.software
Hope in 7.6 this will be fixed.
