Filters missing from module

-- HikaShop version -- : 5.0.3
-- Joomla version -- : 4.4.3
-- PHP version -- : 8.1

Hi!

I have 3 filters in a module, after upgrading to Joomla 4 one filter (Country) does not appear on the filter module in Greek language but it does in English and French. I checked the module, created new ones to test and same thing is happening. I removed all overrides still nothing.

Where could this be coming from?

Thank you

Update,

Now, after translating the custom field, it doesn't show the country filter at all in product listing page but it shows it in product page.
I will send you login if you could take a look?

Thank you!
