There are three default arguments that are relevant here, but seeing that you set save_total_limit=1 I am not sure what else could be being saved…

save_strategy (:obj:`str` or :class:`~transformers.trainer_utils.IntervalStrategy`, `optional`, defaults to :obj:`"steps"`):
    The checkpoint save strategy to adopt during training. Possible values are:


        * :obj:`"no"`: No save is done during training.
        * :obj:`"epoch"`: Save is done at the end of each epoch.
        * :obj:`"steps"`: Save is done every :obj:`save_steps`.


save_steps (:obj:`int`, `optional`, defaults to 500):
    Number of updates steps before two checkpoint saves if :obj:`save_strategy="steps"`.
save_total_limit (:obj:`int`, `optional`):
    If a value is passed, will limit the total amount of checkpoints. Deletes the older checkpoints in
    :obj:`output_dir`.
