Mikrotik 3 API quote problem

I have a problem with sending the sentence which contained quoted word.
When i send any sentence with unquoted word it passes, but the quoted word don’t.
The format is correct, and it seems like MT3 bug.

For example, i can send this:
/interface address add address=192.168.1.1/24 interface=ether1
and i can send this
/interface address add address=192.168.1.1/24 interface=ethernet port
but i can’t send this
/interface address add address=192.168.1.1/24 interface=ethernet port comment=lan port
and i can’t send this (which should work)
/interface address add address=192.168.1.1/24 interface=“ethernet port”
or this
/interface address add address=192.168.1.1/24 interface=“ethernet port” comment=“lan port”

So, why i can’t use API to send quoted sentences ?

I get message:

!trap
=category=1
=message=input does not match any value of interface

NOTE: i wrote the commands above like i using the telnet or ssh becouse it’s easier to read - the commands are send correctly via MT API.
