Wrong language for custom fields in block checkout

Good day,

I have created some custom fields which are added to the block checkout, which works great.

However, once it comes to translating these fields with WPML, things fall apart.

I have already translated the field labels and the field values via WPML’s string translation page, just like for any other plugin or resource. The block checkout only displays the original language though, it basically ignores the translations, which are definitely there, and just displays the original label value that I entered when creating these fields.
