SearchKit - arithmetic not working

When you have custom field that is number or integer, arithmetic will not work. How to reproduce this issue:

1. Create custom set on contact
2. Create custom field type integer name "testinteger"
3. Create search kit on Contact
4. Add "testinteger" field
5. In field transformation change "testinteger" to arithmetic like on picture bellow
6. Now when you click on search, you will not get any result
