Invalid format for filter in Explore

Hi,

I have a node with a date field parameter that I am attempting to filter in Explore. Perviously it was my experience that when in Filter and I selected a node and a parameter the histogram would be shown with the extremes set to the min and max. Now when I do this the limits are highlight and have the error message of invalid format. I can set a date for between min and max to ranges I know are valid and all nodes will be excluded. I have checked the node parameter data type and they are all good. Note: at one point in the evolution of the database the data type was incorrectly set to string, it was later recast as datatype and all queries to check show that all the relevant nodes have the parameter as datetype.

MATCH (p:Patent) WHERE p.filed IS NOT NULL

RETURN

count(p) AS total_with_filed,

count(p.filed.year) AS converted_to_date_count;

I have refreshed perspectives, I have cleared cache, I have stopped and restarted the database, I have quit and relaunch.

Any other solutionS

I am using Desktop 2.1.4 and the database is version 2026.4.0
