Hue group brightness update

[Blueone]

I have connected my philips hue bridge to domoticz. I have several groups with lights which I use. The problem is the group brightness isn't updating when I change the brightness in a other app, are there possibilities to update the group brightness automatically? I already use the script described here: https://www.domoticz.com/wiki/Philips_H ... Hue_Status, but that one didn't work.

I also notice that some lights also don't have the brightness level, when i check the devices tab I see the following:

Some lights do have a set level and some don't while it are exactly the same bulbs. The lights which doesn't have the set level aren't updated either while I can set the dim level from domoticz. Does anyone have an idea what is going wrong here?
