Your input is an AVS Script from what I see, which handles 4:2:0 Type 1 but not 4:2:0 Type2!
So, the chroma location is wrong, hence the "bleeding".
Chromaloc seems like a big misfire to me at this point, since so many encoders and decoders don't actually encode/decode differently based on the parameter. Other than for HDR Blu-Ray, which requires chromaloc 2, I recommend leaving it at the default for broader compatibility.

At 4K resolutions, getting it wrong is pretty hard to see, but the lower the frame size, the more screen area an error will take up.
