Hugingface Bart outputs summary in which first word is ignored

hi,
i am trying to finetune BART for text summarization.But the output summary does not show the first word
Example--Bart output-''ings are s o multifocal patchy homogeneous areas of ground glass attenuation with septal thickening in both lung fields '
Actual output--''findings are s o multifocal patchy homogeneous areas of ground glass attenuation with septal thickening in both lung fields .''

i am using pretrained bart-base
tokenizer--
text_input_ids = tokenizer.batch_encode_plus([text],max_length=512,pad_to_max_length=True,
return_tensors='pt',truncation=True)

Look at the tokenizer configuration and decoding step in the summarization script. The issue likely relates to how special tokens (like BOS/EOS) are handled during generation. Start by examining the tokenizer's encode/decode methods and the model's generate call. Verify the output by comparing token IDs before and after decoding to see if the first token is being dropped.
