`cmip6_monthly` always shows band info for `clt` variable

[Joshdpaul]

I think something must be amiss with the ingest for this coverage, as no matter what variable is requested the variable metadata in the returned netCDF describes the clt variable:

Requesting tas variable (encoded as 13):

https://zeus.snap.uaf.edu/rasdaman/ows?&SERVICE=WCS&VERSION=2.0.1&REQUEST=GetCoverage&COVERAGEID=cmip6_monthly&SUBSET=varname(13)&SUBSET=ansi(%221950-01-15T12:00:00.000Z%22)&SUBSET=lat(61.5)&SUBSET=lon(-147)&FORMAT=application/netcdf

Requesting pr variable (encoded as 4):

https://zeus.snap.uaf.edu/rasdaman/ows?&SERVICE=WCS&VERSION=2.0.1&REQUEST=GetCoverage&COVERAGEID=cmip6_monthly&SUBSET=varname(4)&SUBSET=ansi(%221950-01-15T12:00:00.000Z%22)&SUBSET=lat(61.5)&SUBSET=lon(-147)&FORMAT=application/netcdf

both result in a dataset that has the clt metadata, though the values are clearly not for clt:

In the Rasdaman UI, I see this clt info under the <covMetadata>/<bands>/<data> tags, and it seems to be the only variable listed here. How do we get the right metadata to appear in the xarray.Dataset when requesting the data as netCDF?
