In English Wiktionary all collapsible elements are collapsed and can't be accessed

Kiwix version 2.3.1 (installed through flatpak) OS Linux Mint 21

I have downloaded English Wiktionary (text-only) file for offline use in Kiwix, but the translation table is collapsed by default and there is no way to expand it. No matter how many times I click it. It also affects declension data because in English Wiktionary it is shown in collapsible element.

It is probably some problem with parsing, since Ukrainian Wiktionary seems to have this elements expanded with all the content shown.
