Dashboard filter limits the list selection

I have a dashboard filter that is used to select specific annual reporting periods. For example:

2025-2026

The field should include all the reporting periods for each data model.  Meaning if a data model has reporting periods that range from 2022 to 2026, the selection list should include:

2022  - 2023
2023  - 2024
2024  - 2025
2025  - 2026

However, for one particular field, the listing does not include anything earlier than 2024 - 2025 (See screen capture)

However, if I select Include all...My results in the dashboard widget will include data from all 4 report periods. 

Any suggestions as to why this is happening?
