Not finding all nodes in the KNIME installed in my PC

Hello,

I have just installed KNIME Analytics Platform 5 in my computer. In the nodes section, I see only few nodes from each category. But I don’t see the nodes: Partitioning; Decision Tree, SVM, etc. Even I searched by typing the node names in the search box- no luck. I installed all the extensions as well, still I don’t see the above mentioned nodes. I think I am missing something. Your response will be of great help.
