ACF content doesn't load on custom taxonomies

[tavux-ratkaisut]

Hi!

First impressions about this plugin are great.

I have a setup, where content on pages are managed by ACF flexible layout, where each section is essentially its own block.
So Classic Editor, not Gutenberg.

Everything seems to be working fine, except for these above mentioned blocks on a custom taxonomy.

Saving content on language A on this taxonomy, causes the content to go blank on language B. The data is still available in the Database. By "going blank", I mean that the fields on the admin panel are empty. This problem is visible on the frontend also, no content is being displayed.
No errors on Query Monitor or in the browser console, on either side.

Multilinguality is handled by Polylang.

The site is quite big and complex, so I'll try to create a small reproduction where all other possible variables have been removed.
But currently, disabling Surge makes the problem go away.

I'm creating this issue now, if you happen to have an idea on what could cause the problem. I'll get back here with a small reproduction.

Any luck on reproducing/solving this?
