This is a bug in the toolset - thanks for telling us...
It happens when the project is configured to only hold resources in the webcontent (not in the source part). Please change your project configuration (.ccproject file in main directory of your project) to;
Code:
<project ...
resourcesinsource="true"
resourcesinwebcontent="true"
...
Then you again see all tabs.
We will fix for next update.
Kind regards! Björn
