City filter options disappear when I select In a date filter any 2020 date

I have a COVID cases fact table, a date dimension table and a cities dimension table. I have filters to click and select the city and the date, when I select 2020 in the date the city filter options disappear, if I do it with 2021 or 2022 it works fine and does not disappear. In the fact table there is data in 2020 for any city.

Here's a short video of what is happening:  https://gyazo.com/f9ebe87926f1039fb5e3a30e4d1ec5c1
I have also put the tables in order to make it more clear, (sorry the names are in spanish), I don't understand why could be this happening, when I filter the date, those cities ID are appearing in the fact table and should linked to the cities table, works fine with 2021 and 2022 dates but not for 2020.

I have the city and date table related to cases fact table with one to many relationship: https://gyazo.com/8260dceb8015c79afad4c3fda4322589

Any help is appreciated, thanks!
