problem with GBrowse2 search

Hi,

I am moving from GBrowse1.69 to GBrowse 2. The .gff works fine for GBrowse 1.69, so I think .conf is the problem. For GBrowse.conf I keep it as installation(except add my directory for my own project), for the project.conf file it is as follows(it is for displaying human genome data):
[GENERAL]
description   = annoproject
database      = annoproject      
default tracks = GAD:region
initial landmark = chr1:143000..180000
default width = 800
automatic classes = chromosome cytoband gene
[annoproject:database]
db_adaptor    = Bio::DB::SeqFeature::Store
db_args       = -adaptor memory
                -dir    /var/www/html/gbrowse2/databases/annoproject
# OMIM the [TRACK DEFAULT] and [TRACK]
When I search "chr1" --- it returns "20 matches",but no graph display. When I search "chr1:100000..110000"--- it returns"landmark is not recognized". I wonder if I miss any thing in the .conf file. The attachement have pictures that show what the error is.
