ESLint ui rules presets work incorrectly: "Error (Default)" produces warnings; "Warning" does not work at all.

Steps to reproduce

1. vue create test or create project in vue ui;
2. Select default template;
3. Open vue ui and in Configuration -> ESLint configuration -> select config Strongly recommended or Recommended;
4. npm run serve -> no any warnings (however, warnings must be shown. Regarding this issue the ticket No eslint warnings on initial "npm run serve"  #3065 already opened);
5. Open App.vue, simply re-save it (or make small changes) -> in terminal problems are shown as "Warning", however in Configuration -> ESLint configuration -> Rules tab all rules are set as Error (Default) <--- THIS IS THE FIRST ISSUE;
6. Open vue ui and in Configuration -> ESLint configuration -> Rules tab change Error (Default) to Warning for the rule vue/max-attributes-per-line or vue/component-name-in-template-casing (those two produced warnings at the step 5);
7. Stop launched npm run serve at the step 4 (without this, changes in ESLint Rules are not applied);
8. npm run serve -> no any warnings/errors;
9. Open App.vue, simply re-save it (or make small changes) -> in terminal some problems are shown as "Warning" and those problems, for which we changed presets from Error (Default) to Warning at the step 6 are not shown at all <--- THIS IS THE SECOND ISSUE.

What is expected?

Error (Default) preset should show problems as errors in terminal.
Warning preset should show problems as warnings in terminal.

What is actually happening?

Error (Default) preset shows problems as "Warning" in terminal.
Warning preset shows nothing (work as "Off").
