Bug: Negative Y values don't display on map for "Approx. surface height" layer

[Jereaux]

In Cubiomes-Viewer v 4.1.1, when biomes with high/low weirdness generate negative Y values, the Y value no longer display in the upper right hand corner next to the biome name when hovering over the map in the "Approx. surface height" layer. The Y value is still displayed for positive values, but no value is displayed when you move from a positive Y value to (what I'm assuming) is a negative Y value.

The search condition for finding Y values below 0 does still work though. Just not the display.
