Map link label macros not working in 6.0.0 beta?

[codemaschine]

Hi all!

I'm trying to add some throughput values to link labels in my map. I realised that there's a new notation since 5.4 for the macros, but either it's broken or I'm simply too stupid. Please help me figuring out which one is true ;-)

The Mikrotik host is called gateway01 and the item key for the interface speed is net.if.speed[ifHighSpeed.18]. "Latest Data" shows the correct 10G. My link label is

Link Speed: {?last(/gateway01/net.if.speed[ifHighSpeed.18],0)}

I tried a lot of different combinations without any success. Where's the error?

It's not a beta release, but with yesterday's Nightly Builds, I was able to use the following notation:

In: {?last(/Zabbix server/net.if.in["enp0s3"])}
Out: {?last(/Zabbix server/net.if.out["enp0s3"])}
