FAST-iCLIP/docs/GRCm38/exons.bed has the same start and end coordinate

[Shirleyyyyyy]

Hi,
The top 5 lines of FAST-iCLIP/docs/GRCm38/exons.bed looks like this:
chr1 3102015 3102015 ENSMUSG00000064842 . +
chr1 3205900 3205900 ENSMUSG00000051951 . -
chr1 3206522 3206522 ENSMUSG00000051951 . -
chr1 3213438 3213438 ENSMUSG00000051951 . -
chr1 3213608 3213608 ENSMUSG00000051951 . -
they have the same start and end coordinate on chromosome. Is there something wrong? And I also checked the 3UTR.bed and 5UTR.bed, they also are not consistent with tracks on ucsc genome browser. Could you please tell me how you get these three files, so I can check what's wrong with them.
Thanks!
