Law / I got national visa refusal on point 10. [7]

Hello to the readers, i hope you guys are doing well. I recently applied for a student national visa, and it got rejected on point 10, (as my intentions are other than studying in poland), but the thing is I am already taking online classes and been through all of the semester already, I didn't understand why the Polish consulate refused the visa, I know it have something to do with supporting documents, can someone please explain what extra documents should I present to consulate for point number 10? Any help will be appreciated, thank you.
