Possible bug in paper trading?

I started a simple strategy to see how the paper trading simulation worked. When I start the simulation, the benchmark does not start at a 0% return, but my algorithm does. Is this due to the 15 minute delay? I put a screenshot here. It seems like the benchmark should start at a 0% return as well.

Your benchmark has a prior trading day, your algo does not

Which, thinking about it, is a bug. The benchmark should be the equivalent of buying the benchmark at market open on the first day. Otherwise it isn't a fair comparison

Exactly. It doesn't make sense that they don't start at the same rate of return, namely 0. I wonder if this is a problem in the live version. Can anyone confirm or deny?
