Member Director Numeric Filter inaccurate

Hi,

I have a custom numeric field for users and want to add the filter to the Member Directory search box. When I do add it the numbers shown in the range values are correct. But when I use the toggle to show members with those numbers they are not displaying members for certain values. For example I definitely have users with the value 81 and users with the max 115 but when I select these options using the toggle it says not found but if I set the values to 81-98 it will show the user with 81. Is there something I can do to fix this?

Thank you.
