Graph labels and trend line for best score statistic are duplicated across benchmarks and do not match

Despite using 4 different <name> values in the benchmark.xml file, for four different <solverBenchmark>s , the final <name> element value is labelled at the bottom for all four best score statistic graphs (next to the red line); the trend lines for at least the soft score (hard/medium/soft scheme used) are also duplicated across the graphs.   I'm using "default" values for the benchmarking reporting and not specifying anything else outside of the <solver> elements except what you see below.   In this example, all the labels I see are BENCHMARK 4, which is the name of the last solverBenchmark.

<benchmarkDirectory>benchmark</benchmarkDirectory>
<parallelBenchmarkCount>AUTO</parallelBenchmarkCount>
<solverBenchmark>
<name>BENCHMARK 1</name>

</solverBenchmark>

<solverBenchmark>

<name>BENCHMARK 2</name>
