The problem is described in the title (and see attached image). I also wonder why it doesn't provide a model option in the Defect4JExperiment.sh when it calls sequencer-predict.sh as shown below:
echo "Generating patches for ${col1}_${col2}"
$CURRENT_DIR/../sequencer-predict.sh --buggy_file=$BUG_PROJECT/$col3 --buggy_line=$col4 --beam_size=50 --output=$DEFECTS4J_PATCHES_DIR/${col1}_${col2}
