Facet for years doesn't seem to work properly

[agentilb]

Exemples:

• When you want to modify the selection of years in the facet, it seems there is a strange behavior: if I want to remove year 2024, it removes also most of 2023.
• And when we remove oldest years, then most of 2024 records disappear from the result
