Date Map transform issue

I’m trying to map-transform a date (month and weekday) to another language. Unfortunately, I’m unable to transform both of them together, but only separately.

Is there a way to transform
Monday, February
to
Bon, Mo ?

I have a date.map in utf-8

Monday=Bon
Tuesday=Sai
...
January=Eski
February=Mo
...

date.item

DateTime Current_Date "[%1$tA, %1$tB]" { channel="ntp:ntp:f7a3ab6c:dateTime" }

this works

DateTime Current_Date "[MAP(date.map):%1$tA]" { channel="ntp:ntp:f7a3ab6c:dateTime" }

this doesn’t

DateTime Current_Date "[MAP(date.map):%1$tA], [MAP(date.map):%1$tB]" { channel="ntp:ntp:f7a3ab6c:dateTime" }
