String segments resests after synchronizing translations

[Azadron228]

I am encountering an issue where some string segments reset after synchronizing and publishing translations. Specifically:

Only certain pages are affected, and within those pages, only some strings reset.
The resetting string segments are being re-inserted into the wagtail_localize_stringsegments table after synchronization.
Other pages and string segments of same page model work as expected without issues.

Environment:

wagtail-localize: 1.8
Django: 4.0.7
Wagtail: 5.2
Database: MySQL

This is how i created page

class ChairMemberPage(SitemapMixin, Page):
    parent_page_types = [ChairPage]

    photo = models.ForeignKey(
        "wagtailimages.Image",
        null=True,
        on_delete=models.SET_NULL,
        related_name="+",
        verbose_name="Фото",
    )
    position = models.CharField(max_length=100, verbose_name="Должность")
    email = models.EmailField(verbose_name="Электронная почта")
    subjects = RichTextField(verbose_name="Основные преподаваемые дисциплины")
    education = RichTextField(verbose_name="Образование")

    info = StreamField(
        [("paragraph", blocks.RichTextBlock(label="Параграф с доп. информацией"))],
        verbose_name="Дополнительная информация",
        blank=True,
        null=True,
        use_json_field=True,
    )

    content_panels = Page.content_panels + [
        FieldPanel("photo"),
        FieldPanel("position"),
        FieldPanel("email"),
        FieldPanel("subjects"),
        FieldPanel("education"),
        FieldPanel("info"),
    ]

    search_fields = Page.search_fields + [
        index.SearchField("position"),
        index.SearchField("email"),
        index.SearchField("subjects"),
        index.SearchField("education"),
        index.SearchField("info"),
    ]

    class Meta:
        verbose_name = "Сотрудник кафедры"
        verbose_name_plural = "Сотрудники кафедры"
