Advanced filtering not filtering out certain words

[NielVE]

Howdy,

I'm having some issues with filtering out values that contain either the word "DRUM" or "IBC" when using the advanced filtering option.

As you can see here here I entered "does not contain DRUM or does not contain IBC" but as you can see these values still show up. When I use "contains" it works and only shows the items that contain "DRUM" or "IBC" but it does not seem to work the other way around.

I have no idea why this is the case.

Any help would be much appreciated!

Thanks!

Niel
