Ignore list: Misleading entry "Presets do not contain property key"

[GerdP]

What steps will reproduce the problem?

1. Have some unit test data where lots of objects have a tag expected_code=*
2. Run validator
3. Find lots of "Other" messages Presets do not contain property key - Key 'expected_code' not in presets.
4. Select that entry and click Ignore and click "Whole group"

What is the expected result?

Ignore list shows an entry for the specific tag key 'expected_code'

What happens instead?

Ignore list show an entry Presets do not contain property key. Since I don't want to ignore all those messages I got nervous.

Please provide any additional information below. Attach a screenshot if possible.

Found this while working on data for a unit test. In fact the ignore list contains the wanted specific entry, it just doesn't show it unless you click on the +. Not sure if this can/should be fixed.
