contour plot showing colour problem at level 0

Hi,
I'm using RAD studio 10.4, and my application is compiled as 64 bit C++.
TeeChart Build v2020.30.200525

I am using a Contour chart with custom levels & colours.

contour Level 0 (upto value) is always drawn in black, despite the colour defined.

I've attached a picture that shows this. Level 0 in the legend "UpTo" value is 580. The data set has values starting from 290. You can see large black areas which I would expect to be a dark blue colour (level 0 colour in the legend.

I haven't included any example code BUT I can easily reproduce this in the chart editor / designer by manually entering values that should fall into the Level 0 zone.
