I noted that What's New page promotes a slippage bug to be solved in 1.52.0 but this version seems to be not available yet because the actual beta on the download page is 1.51.9. Did you already get 1.52.0 there?
Sorry, I misunderstood your last post. I thought that it's fixed in 1.51.9. So we'll see if it is fixed in the next version.
Nevertheless it's worth noting that all previous backtests should be done again as Slippage > 0 has been default.
