The field Notes does not working properly.
Inserting for example for a Pump under Notes "Design Flow 120000" and saving the file, at next file opening Notes contains "{\rtf1\ansi\ansicpg1252\deff0\deflang1036{\fonttbl{\f0\fnil\fcharset0 Microsoft Sans Serif;}}
\viewkind4\uc1\pard\f0\fs17 Design Flow 120000\par
}" and clicking the Notes editor nothing is there.
