ACX Reagents cannot be added for the second time

PROBLEM:

Use ACX Reagents Form tool to add compounds for the first time. Everything is OK.
Return to ACX Search window, use structure name to search for the second time. The searched data cannot be added, as the "Add" button is grey.


WORKAROUND:

Close the "Select & Add Structure" window when the "Add" button is not enabled, then click "Add... " button on Reaction Toolbar. Doing the search will enable the "Add" button in "Select & Add Structure".
