Using the page name as the language name causes issues

[noidar]

Hello,
I am using next-i18next as i18n solution, my page structure is pages[country].
therefore the URL will be http://localhost:3000/de[language]/de[country]/otherpage
router.push('de/otherpage') it swaps de URL to http://localhost:3000/de/otherpage but should be http://localhost:3000/de/de/otherpage
here is the example:

Thank you.
