Maybe I’m doing something extremely dumb.

Can’t preview a filter in the preview window, **exported fonts don’t seem to apply the filter.**  
Steps:  
1.Create a new file  
2. Add some monolines  
3. Open noodler (or offset) filter  
4. copy parameters from the filter  
5. paste parameters in Master  
6. Export  
Result:  
Zero, empty  
Expected:  
Filled object

Any troubleshooting help appreciated.

Downloaded **stable** version but also doesn’t work.

Filter parameters cannot be applied in the master, only in the instances.
