The filter system not working for some columns could be due to a few reasons:
1. Front-end performance issues: You might be experiencing temporary display problems. Try clearing your cache and refreshing your screen.
2. Incorrect filter setup: Ensure you've set up the filters correctly:
โข Click the "Filter" button above the table
โข Select the column you want to filter
โข Choose the appropriate comparison operator
โข Enter the value you want to filter by
If these steps don't resolve the issue, it might be a more complex problem. In that case, you may want to request human assistance for further troubleshooting.
