From your description the extension didn't found record with Net Profit: All in backtesting results. The problems there can be in strategy or in TV language. First of all - try to increase the maximum waiting time in "Options & Tools". Probably your strategy didn't finish at the time when waiting limits for strategy results is end and extension trying to parse results. The second - screenshot with chart and error will be helpfull.
