How to process local that is already split adjusted?

I am running some local back testing experiments. I imported the split adjusted data into LEAN. However, when I run the backtest, LEAN still adjusts the data for split. This creates a big price jump when a split happens. I tried to use difference data normalization mode, but it doesn't help. Does anybody know how to prevent the data adjustment that is seemly default in LEAN? Thanks a lot!

Update Backtest








I found out that the files in Data/equity/usa/factor_files store the split information. I manually updated this file to reflect the adjusted data. Now the prices match the imported prices. Thanks!
