[solved] Can't get any filter to work, how to troubleshoot or reinstall

[ghost]

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.
