Smart meter binding - Negate property didn´t work after upgrade to OH4.1

I used the binding since I have OH running and everything works fine.
Yesterday I´ve upgraded to OH4.1 and now during the day I realise the power send to the grid isn´t displayed negative anymore.

I have set Negate property = 1-0_1-8-0:5:1:status in the thing configuration
OH 4.1 is running on a Pi3. Java is openjdk 17.

I hope somebody can help

Thanks in advance for your time
