SBO Tests yield wrong result (at least in JSON)

[Schmoho]

Why is this result "failed"?

    "test_metabolite_sbo_presence": {
      "data": [],
      "duration": 0.0049783941358327866,
      "format_type": "count",
      "message": "A total of 0 metabolites (0.00%) lack annotation with any type of SBO term:",
      "metric": 0.0,
      "result": "failed",
      "summary": "[...]",
      "title": "Metabolite General SBO Presence"
    }

Same happens with most SBO checks as far as I can tell.

The html report shows a green box with 100% though.

Memote version 0.17.0

Looks like a bug 😉
