[solved] After upgrade don't work Total bandwidth and 95th

[ckat]

After upgrade from 0.8.7b to 0.8.7e all graphics with
Total bandwidth and 95th Percentile don't show values

Look at example
CDEF:cdefa=a,8,* \
CDEF:cdefg=b,8,* \
AREA:cdefa#00CF00FF:"In " \
GPRINT:cdefa:MAX:"Max\:%8.2lf %s" \
GPRINT:cdefa:AVERAGE:"Average\:%8.2lf %s" \
GPRINTMIN:"Min\:%8.2lf %s" \
GPRINT:cdefa:LAST:"Now\:%8.2lf %s" \
COMMENT:"Total In\: 0 bytes\n" \
LINE1:cdefg#002A97FF:"Out" \
GPRINT:cdefg:MAX:"Max\:%8.2lf %s" \
GPRINT:cdefg:AVERAGE:"Average\:%8.2lf %s" \
GPRINTMIN:"Min\:%8.2lf %s" \
GPRINT:cdefg:LAST:"Now\:%8.2lf %s" \
COMMENT:"Total Out\: 0 bytes\n" \
HRULE:0#FF0000FF:"95th Percentile" \
COMMENT:"Max peak mbit 0

How fix the problem?
