Query Tab is not selecting the Default schema which already selected in the First Query Tab

After creating a First Query Tab and selecting some xyz schema and ran some queries, so if we create a second Query Tab or 3rd Tab then it's not using the same xyz schema (Which we already selected/used schema in the First Query Tab) automatically and. It means when we try to create a new query tab's after creating a first tab then again, we have to select the schema for the new query tabs.
