Time integration inaccuracy

I implemented time integration of the convective diffusion flux, as I learned from this forum. It works as supposed, but it is rather inaccurate, mass balance deviates ca. 10%. Then I integrated the flux out of the system (surface integration of the total flux magnitude), exported the table in Excel where I made time integration manually. Now, the mass balance agrees with less than 1% accuracy. Hence, can I improve the time integration somehow in Comsol? It would save a lot of time.
