cypress grep filter not working correctly when define tag via class

[CuongPham9212]

in my project, I'm using cypress grep tag to filter spec and run in CI
I declare the tag in the class
example
../support/taglist.js

export default class CommonTag {
  static smokeSuite = 'smoke_suite';
  static web = 'web';
}

and in the spec file using tag to filter:
e2e/event.spec

describe(
  'page event',
  {
    tags: [CommonTag.smokeSuite, CommonTag.web],
  }, () => {
  it('Click on element', () => {
     cy.get(selector).should('be.enabled').click();
  });
  })

then run the command:
npx cypress run --config 'baseUrl=https://example.com,retries=0' --env 'grepTags=smoke_suite+web,environmentName=integration'

but the log return as run all specs and filter at run-time instead of filter specs with tags first then run it:
loading ./cypress.integration.json
loaded settings for environment integration
@cypress/grep: filtering using tag(s) "smoke_suite+web"
@cypress/grep: will omit filtered tests
grep and/or grepTags has eliminated all specs
grepTags: smoke_suite+edge
Will leave all specs to run to filter at run-time

the result is: it will run all specs but will return 0 passing when specs doesn't contain tags and will return 1 passing (for example) when running specs with tag pass via class -> it makes test result report display incorrectly

The question is: why it is running correct when past string to the tags but it isn't running correctly when add tags via class
