Is there an existing issue for this problem?

I have searched the existing issues

OrcaSlicer Version

2.3.0.; 2.3.1.

Operating System (OS)

Windows

OS Version

10

Additional system information

CPU: intel i7 4790k
GPU: Nvidia RTX 3070ti
RAM: 16 Ddr3 1866 MHz

Printer

Ender 3 V3 Plus with Co-print Multicol kit

How to reproduce

Open a random stl. I use an stl from Hueforge
Wipe tower on; no sparse layer on
These are my color changes from Hueforge:
"Start with Hyper Black
At layer #15 (1.28mm) swap to Hyper Grey
At layer #21 (1.76mm) swap to Fast White
At layer #23 (1.92mm) swap to Hyper Yellow
At layer #26 (2.16mm) swap to Hyper Orange for the rest."
Update the g-code
now i have color changes at 15, 28, 28, 29. And 29

i doesn't even exist on the print.

Actual results

After the previsious steps the color changes are at the wrong layers.

Expected results

Orca should give me a g-code with the correct layer's color changes at 15, 21, 23, 26.
