[Vuejs]-Vuelidate validates on page render

As the page renders vuelidate will run all the form validations. That’s how vuelidate works.

You need to check form for dirty along with it being invalid.

$v.$dirty() && $v.$invalid()

When you use $v.$touch() or $v.$reset(), vuelidate marks the form as dirty.

Please read https://vuelidate.js.org/#sub-v-values to understand the importance of these methods.
