Problem displaying/impoting existing mesh maps to file

[Mischel2659771122ob]

I have already baked mesh maps, such as normal, AO, etc. and imported them to the shelf.
I hooked the imported maps into the fitting spot in the Texture Set Settings.
However, my maps all show up with a big number (1) printed on top of them in the shelf and the maps are not showing up in the 3D, nor 2D view.

There is an error message: Failed to decode bitmap.
My file format is png. What can be wrong with it?

Hi,

The big number is not a bug, it's due to your nomenclature that tells Painter that this is part of a series of UV tiles.
The error that you have doesn't explain anything to me, would mind sharing your file that shows that error? I could maybe find the source of the issue. 

Thank you,
Kind Regards,
