Problem with eye textures of Genesis 8.x

[MyRho]

Hi.

I've found a strange problem with some textures for the eyes of my Genesis 8.x characters.
When I try to change the colour/texture of the irises and/or pupils octane won't render the new ones - instead of them it renders the old ones which I don't want.
I've tried to change the textures manually or put them by drag and drop onto the irises and pupils - but octane still renders the old ones.
Even if I to reload the scene or starting a final render - still the old ones.
I tried to set the material to blank materials but even that doesn't change anything.

How can I change the textures?
Maybe someone can help me with that?

I assume you've probably restarted the program since then? Does it still do it?
