Traditionally (ie Classic and AE) it has been possible to print lines with Dates and descriptions with zero values and no amount is dislayed; merely a blank field. Now in AR2018 all zero values print...
Agreed, I just had to help someone with this a fortnight ago. Almost went crazy before I remembered how to do the Add note lines trick.
(Can it be more obvious that there's a hidden right click add note lines option as well as having an optional "Suppress 0 value lines on professional invoices" option?)
