How to reproduce

Tried loading this model https://makerworld.com/de/models/1705128-cute-penguin#profileId-1808654 as pre-painted 3mf.

The remap filament function, however, seems to only consider the painted colors, but always takes the base color as 1.

Here is a video of the situation

Actual results

This model has a yellow base color with white, red and black being painted on.

After this re-mapping yellow<>red and black<>white should be switched.

However, the result is this. Everything has been switched as expected, except for the yellow which seems to be considered as 1 = black and is therefore mapped to white.

Additionally after the mapping the base color has no influence any longer, all colors are now determined by the painting.

Expected results

I can't produce the correct result with the remap feature, as whatever base-color I choose it is always considered to be the same color as the beak and feet.
But it should look like this

(colored it manually to look like this)

Project file & Debug log uploads

You can download the 3mf from https://makerworld.com/de/models/1705128-cute-penguin#profileId-1808654
I only opened it in OrcaSlicer, changed printer and filaments.
