MACROs are not converted to value when used in unit at item definition

{CURRENCY} is a global defined MACRO (administration/macros)
{$TAPO_PRICE_UNIT} is a demplate defined MACRO on HOST

neither one type is converting to value

I kind of cannot find that you can use user macros in "unit" field...
