Initially it was Number. But it was displayed with comma like 2,023. I looked for a solution and found this:
When I changed type to Text the filter broke. I returned type to Number with no success.
The only way to resolve this issue: create new attribute with different field name because when you delete attribute it actually just becomes hidden and when you REcreate attibute with the SAME field name you have all your thousands listings with all broken values back.
