Pop-up menu names do not change with Eclipse plugin development

Eclipse plugin development is adding menus to pop-up menus.
The menu itself can be added and works, but changing the name of the menu does not take effect.

The menu is defined by the following code:

<extension point="org.eclipse.ui.commands">
 <command defaultHandler="link.arata.mybatishelper.MyBatisHelperCommand"
 id="link.arata.mybatishelper.MyBatisHelperCommand" name="%XMLFileOpenAction.label">
 </command>
</extension>

The name itself is defined by its properties and is described as follows:

XMLFileOpenAction.label=Open the corresponding XML file

The first name you define is correct, but changing the value of the property does not change the name you defined first.
If you change other parts of the program, that part will be reflected properly.
How does it take effect?

Tried

• If you set it to literal or property values, it may change sometimes, but it doesn't seem to be legal
• Project clean.

Environment

• MaxOS 10.11.1
• Eclipse for RCP and RAP Developers 4.5.1
