When i use column formatting for a number field in a gallery view and enter the advanced mode to use json formatting, all formatting disappears.
I've created a list in sharepoint online with the title and a number field. Than i changed to gallery view and created some conditional formatting for the number field, which worked:
The logic wasn't enough, so i entered the advanced mode and all formatting disappeared:
Other fields type text or yes/no are working in gallery view and formatting for number fields works in normal list view. But i want the formatting explicit for a number field in gallery view.
Please help me 
Now with a gif. In the moment i click on the advanced mode button, all formatting disappears immediately, although the formatting still exists in json formatting.
