problem with get_mut_type(data, type = "dbs", predefined_dbs_mbs = FALSE)

[riccardobergamin]

i am running the function get_mut_type(data, type = "dbs", predefined_dbs_mbs = FALSE) on a GenomicRanges object which has the form

But i am getting apparently wrong dbs context

i am not understanding if it is a problem of the input object or a mistake of the function.
Thank you very much for the help
