When we save a filter's settings on the backend the "Values" we've added are emptied. Attaching screenshots of before saving and then after saving.

Hi,

The filter system will automatically use the values of the custom field.
There is no need for you to enter them again here.
The values in the filter are to be used when you want to have ranges.
For example, if you have a filter on price, and you want choices like : from 0 to 100€, from 100€ to 200€ etc, you would enter the values 100, 200, etc in these value inputs.
So these are only to be used with numbers.
