TabbedInterface strange behavior

[itekhi]

I have a home page with TabbedInterface which looks like this:

edit_handler = TabbedInterface([
    ObjectList(banner_panels, heading='BANNERS'),
    ObjectList([InlinePanel('home_info_tab_keys')], heading='INFO TABS'),
    ObjectList([InlinePanel('home_achievement_keys', max_num=4)], heading='ACHIEVEMENTS'),
    ObjectList(Page.content_panels, heading="CONTENT"),
    ObjectList(BaseMixin.promote_panels, heading='PROMOTE'),
    ObjectList(Page.settings_panels, heading='SETTINGS'),
])

Now I sync home pages. When I translate them, InlinePanels from second tab shows in first tab("BANNERS")

InfoTabs Orderable for InlinePanel('home_info_tab_keys')

class HomeInfoTab(TranslatableMixin, Orderable):
    page = ParentalKey("home.HomePage", related_name="home_info_tab_keys")
    poster = models.ForeignKey(
        "wagtailimages.Image",
        null=False,
        blank=False,
        on_delete=models.CASCADE,
        related_name="+",
    )
    overhead = models.CharField(blank=False, null=False, max_length=50)
    title = models.CharField(blank=False, null=False, max_length=100)
    description = models.TextField(blank=False, null=False)
    more_button = models.ForeignKey(
        'wagtailcore.Page',
        null=True,
        blank=True,
        on_delete=models.SET_NULL,
        related_name='+',
    )

    panels = [
        ImageChooserPanel("poster"),
        FieldPanel('overhead'),
        FieldPanel('title'),
        FieldPanel('description'),
        PageChooserPanel('more_button'),
    ]

    class Meta(TranslatableMixin.Meta, Orderable.Meta):
        pass

I think something is happening with InlinePanels, because if I add FieldPanel with text field specified to the second tab, like this: ObjectList([InlinePanel('home_info_tab_keys'), FieldPanel('text')], heading='INFO TABS'),
Now "INFO TABS" tab is showing up only with text field to translate, InlinePanels are still in "BANNERS" tab.
