img db gt features

Hello, I watched that you use two image features (fname_gt, fname)
At first, I thought, img_gt features for image masking tasks like MRM, MRFC etc.
But I see it is used at MLM task, so I'm not sure that you use double features even gt features have different number of bounding box objects.
Thank you

The issue mentions the image features `fname_gt` and `fname`, along with MRM, MRFC, and MLM tasks, but names no files, tests, or entry points. Start by locating those feature names and tracing their use in the masking and MLM data paths; done would require documenting whether both features are intentionally used and why their bounding-box counts may differ.
