C2RCC - Rhow and Rtosa all water pixels are out of range?

Hi, I am trying to use C2RCC on a Sentinel-2 image.

I’ve tried both the regular and the complex neural nets, and in both cases, the Rhow_OOR flag is white over all the water surfaces in the image. C2X Nets seems to have the right range, with no flagged pixels. I am just trying to understand what this means, since the water body I am looking at is extremely variable, with some very clear and some very turbid, bright regions.

It seems unlikely that the entire water body would be out of range for both of these neural nets?

Cheers and thanks in advance for any help!
