resource file with gsn_csm

Dear NCL group,

I am learning how to use resource files now.
And I got a problem with gsn_csm interface.

I know that if I use gsn_csm and set cnFillOn to be True, a labelbar will
be created automatically.
And it is TRUE if I put cnFillOn in .ncl script.
However, when I move this resource to a resource file, I have a filled
contour but no labelbar, even though I explicitly set lbLabelBarOn to be
True.

I have other resources in that resource file.
Some of them work; some don't. cnFillOn is just one example.

Just wondering where I went wrong.
Thank you very much!

Here I list:
1, NCL script (resfile.ncl)
2, resource file in the same directory (resfile.res)
3, I put the test data (cf_grl_airs.nc) and the above two files to the ftp.
4, I am using NCL 6.2.0
5, Linux grele 3.5.0-52-generic #78~precise1-Ubuntu SMP Wed Jun 11 17:14:53
