Linuxcnc/Ethercat config different behavior in movements

I have following Problem with my Linuxcnc/Ethercat configuration(s)

I made a configuration with the Axis GUI which worked really well for me.
The machines Feeds and Speeds are normal, i can jog the Axis flawlessly in all directions.
When i run a job it also works really well. There are no Errors shown in LinuxCNC.

But now i want to change to qtdragon GUI. I set up a new Profile based on the EtherCAT configuration of my Axis Profile.
Now the machine has a weird behavior, when i Jog an Axis it moves only a short distance and stops then without any error messages. Even when Continous Jog is selected. This behavior is on all 3 joints (X Y Z). The jog speed is also way slower than under the Axis GUI. After 2 or 3 Jog attempts the DRO Changes without Motor movement and also no errors in LinuxCNC.

Where can i look for Errors? I compared both ethercat .xml files and hal files in vscode and did not find any clue what can be wrong.
