0.96 + macOS Mojave: blank filetype icons

[max_u]

Hello!
> macOS Mojave 10.14.6 + Xnview MP 0.96
All image files are associated with Xnview (see attachments).
Launch services were reset but all icons are blank. ):
Note: it's not thumbnails — it is filetype icons (jpg, png, gif etc.)

What should I do?

Thanks.

Integration at Settings is empty:

Thanks for feedback.
Prove me wrong, Xnview MP macOS version doesn't have it's own default icon so blank is ok?
