I ran into a similar problem as you have and it was visible in a backtest on the closed positions tab.
It showed bars=0 & with profit or loss, caused by position-sizing Thought maybe there’s a link to your problem.
You should look preferably on the tab orderlist. The closed positions tab doesn’t display the correct entry & close time for some positions with are added to a current position
So if it displays a loss/profit with 0 or 1 bar, it actually could have ran multiple bars, at-least that’s what I suspect and the real entry&exit times can be seen there on tab orderlist. Take a look at each individual trade with more positions on the chart to be sure.
Here’s a pic with my situation in a backtest.
