strange behaviour with filters in list view when using custom field

[slechaix]

Hi,

When I want to use advanced filter in a view, if I use a negative condition like "not equal to" or "does not contain" on a custom field, then I have no result.

My filter is really simple with only one condition:
Model field (cf_801) => does not containt "ABCDE" give me an empty list

Wheareas if I use a positive condition, I have no issue.
Same if I use filter on any non custom field, I have no issue at all.

Do you think it's a bad configuration, a bug, or maybe I'm not using filters correctly ?

Thanks for your help
Steve
