Cannot Export Dataset (Key Error)

[Rifuath]

Got an Error while Exporting the Annotations to Training Datasets.

I have used a custom labelset for my project and have used default settings while exporting.
I have other labels that has zero, which i have not selected using the eye button on the label window
I got the following error while doing that:
