Some Questions About the Box-List File Usage During Training

While analyzing the SlowFast training code, I noticed that in the configuration file SLOWFAST_32x2_R101_SHORT.yaml, under the AVA section, the TRAIN_PREDICT_BOX_LISTS is defined as: TRAIN_PREDICT_BOX_LISTS: [ "ava_train_v2.2.csv", "person_box_67091280_iou90/ava_detection_train_boxes_and_labels_include_negative_v2.2.csv", ] However, in default.py, the GT_BOX_LIST also contains "ava_train_v2.2.csv". This makes me wonder: is it a configuration mistake to use the same file in both TRAIN_PREDICT_BOX_LISTS and the GT box list? Or is it intentional? I'd appreciate any clarification on this.
