Hi, per this conversation, I have migrated Template:Pl:KeyDescription to use Template:KeyDescription. The appearance should be nearly identical as before. If everything is OK, I will migrate Template:Pl:ValueDescription too. If not, please add a comment to the conversation page above, and I will fix it. If the issue is urgent, just revert this change, but please leave a comment explaining what to fix. In the near future, thanks to the new system, all translations will be available in iD editor and possibly other tools! Thanks.
