Look Up Data not displaying for a particular period (time)

Hello BrainsTrust, hoping for input, guidance and hopeful solution from the Glide Community.

I have an issue with data no longer displaying from a lookup collection from a data table for a set period.
Look Up collection pulls data based on calendar quarter which is then displayed in a table. All quarters from 2023 to Quarter 3 2024 are working as intended.
However no data is displaying for Q4 2024… but it IS displaying for Q1 2025.

Also when viewing the user table and the section that the Look Up collection pulls from… the table data for those specific rows ‘pulses’ every 5 secs or so.

When viewed in Layout view the table in question flashes and then scrolls. back to the top (I suspect it is continually looking for data that it can not find - even though the data is there within the data sheet ?)

Weirdly, if I set a filter that links the period within the table where the records are displayed … Q4 2024 does not appear as selectable ???
