Differences between SWAT+ rev. 61.0.2 (official) and rev. 61.0.2.61 (latest) in streamflow and sediment simulation

Dear all,

I ran SWAT+ using rev. 61.0.2.61 (latest) to account for paddy-specific conditions and actions, and calibrated streamflow at a specific stream gauging station.
However, when I run rev. 61.0.2 (official) with exactly the same input data and parameter values, the simulated streamflow and sediment results are very different, as shown in the figure below. Of course, even when I ran rev. 61.0.2 (official) without the paddy-related decision tables, the simulation results still differed substantially between the two versions.

In addition, in rev. 61.0.2.61 (latest), the simulated sediment (tons) often appears as a nearly constant regardless of streamflow, and the simulated sediment values by land use type are also very different from those produced by rev. 61.0.2 (official). What could be causing this issue?

Has anyone experienced similar problems?

If so, what might be causing these differences between the two revisions, and how can the sediment issue in the latest revision be addressed?

Thank you very much for your help.
