Translation with Polylang | 404 errors

Help solve the problem, started translating the site into another language, install Polylang for this, but all the translated pages gives an error 404. In fact Polylang just adds new linked pages, on other AMP plugins this problem does not exist.

Translate URL with Polylang https://www.kushpo.info/uk/statji-uk/stravi-yaki-e-tilki-v-avstralii/amp/
