I could easily reproduce the described behaviour. But I'm a bit hesitant to say it's a bug, since one could say that the 'Custom setting', which is made in the options, is the persistent one (the one that is saved and restored), whereas the setting made in the 'Filter by' menu is the temporary. Similar to the setting for the menu and the option for auto image size.

When looking closer and thinking more about the 'Filter by' menu, I can see some strange thing:

- There's the settings in the option dialog, category 'Browser->File list', which allows setting the filter for thumbnail view and all other views. Also, filters (videos, sounds, ...) can be combined.

- On the other hand there's the sub-menu 'View->Filter by', which does not allow to combine filter and applies for both thumbnail view and all other views.

As one can see, these two filters do not match (unlike the setting 'Auto image size').

During the years I've been using XnView I've never used the 'Filter by' menu. Perhaps someone can give some background info and bring some light and sense into this.
