In section Table of Contents I see the contents of Preparation instead of the reaction in the Reaction section.

This happens because Summary fields in the Reaction section type is configured to display Preparation as a default for section contents. In order to change this behavior try:

1- Log into ELN as a an admin.
2- Browse to Everyone->Configuration->Section Types->Reaction.
3- Right click and select Section Type Configuration.
4- Select Reaction at the top of the tree.
5- From the Summary Field box (to the right) highlight Reaction instead of Preparation.
6- Save and Refresh ELN.
7- Browse to Table of Contents again.
