reproduce:

• open a template with defined macros
• in the add-macro-box enter an existing macro name and a new value
• check the old macro and delete it
• input boxes should still have the new info
• add the new info
• save the template
• reopen the template

at least in my case, the macros still had the old values.

so i deleted them, saved template, recreated them. while the template showed correctly then, the server was still operating with old values and needed another restart!
