These BED files are not really in BED format. The coordinates in each describe a range of "0" bases.
Example of one:
track name="chr6 32721547 rs9275765 BED" description="" chr6 32715344 32715344 chr6 32715605 32715605 chr6 32715986 32715986
Note that the start (column 2) and stop (column 2) are the same value. I am not sure where this was obtained, but for the first data line, this could be:
chr6 32715343 32715344 ==> would designate base "32715344"
BED file specification is here: https://wiki.galaxyproject.org/Learn/Datatypes#Bed
Also, before using many tools that work with BED (or Interval) datasets, it is a good idea to first remove the track (and browser) lines if present. Tools in Text Manipulation can help with removing lines (Remove first lines of a dataset), adjusting data values (Compute), and cutting out columns to reconstruct the proper format (Cut).
