Description
What's wrong?
Reset variable doesn't always work as expected. If the variable was both converted to categorical and had values merged, one cannot change this merge (for example, how many values one wants to have left).
How can we reproduce the problem?
Datasets (Slovenian National Assembly) - Edit Domain.
Change "locality" to Categorical and merge with "Group all except 10 most frequent values". Apply changes. Now change merge to 20 most frequent values. Nothing changes.
What's your environment?
- Operating system: OSX
- Orange version: 3.32.dev
- How you installed Orange: git

Research direction
Reproduce the issue in the Edit Domain widget using the Slovenian National Assembly dataset: convert locality to categorical, merge all but the 10 most frequent values, apply, then select 20 most frequent values. Inspect the Edit Domain entry point and make the second merge selection replace the first; done means the applied data reflects the new merge.
