import LANG from '@salesforce/i18n/lang';
import DIR from '@salesforce/i18n/dir';


export default class multiPageForm2 extends NavigationMixin(LightningElement) {
  lang = LANG;
  dir = DIR;
 

HTML code used for i18n

 <div><p><lightning-input lang={lang} dir={dir}
                    label="Last Name" type="text" value={infoOblName} name="oblName" required=""
                    onchange={scoreHandleChange}></lightning-input></p></div>


Here the combobox options are getting translated but other labels are not getting translated into selected languages
