Cannot Import Internal Palette

[Chaos81]

Using v0.21

When trying to import a palette from "This File", the palette doesn't load.
I've tried on Mac and Windows. Both using Java 21.0.3.

Steps to reproduce problem:

1 - Load file.
2 - Navigate to location you want to look at and set canvas size and codec.
3 - Select Palette->Import From->This File...
4 - Enter the decimal value of the palette location, the size, choose codec and the byte order
5 - Click OK.
6 - Check that palette is loaded.

It works normally if I convert the Palette offset to Hex instead of Decimal (back in 0.16 decimal worked)
