POE Trade : Prefix modifiers filters bug with veiled items

When I try to apply a prefix modifier filter with a veiled items filter, it doesn't work properly. For exemple, I ask 3 prefixes min and the tab shows me items with 1 or 2 prefixes. Or, when I ask 0 empty prefix modifier, the tab just can't show me anything like there were nothing. It doesn't seem to bug with the suffix modifier filter smh.

I tried by searching veiled weapons, don't know for other types.
