Dashboard - Bandwidth graph showing same value twice on scale

Why are two lines on the bandwidth scale showing 1 Mbps? I’m seeing similar behavior in Plex Dash on Android (two 2 Mbps) as well.

It looks like each marker represents +352-ish Kbps, but Plex rounds the numbers to avoid decimals, so you’re left with 352Kbps, 703Kbps, 1Mbps (1055Kbps), 1Mbps (1406Kbps), and 2Mbps (1758Kbps).
