In placeholder settings we could saw wrong names (item names when we should saw display names) :
It is a list of controls inside content editor – names are correct.
It is a name of controls inside experience editor – names are incorrect.
If you want to fix it you have to use patch prepared by Sitecore support team for Sitecore version 8.1 rev. 151003 (Initial Release):
1) Copy the Sitecore.Support.88236.dll into /bin folder;
2) Copy Sitecore.Support.88236.config into /App_Config/Include folder.
