Reset button inconsistancy

I have an issue and I am not sure if this is the correct place to post…
I am experiencing an issue where I have the Show Reset Button for Problems set to false at default. But the button keeps appearing randomly in questions. In the settings it is set to Default, but perhaps I have some other setting (that I could not yet find) that overrides it.
The behaviour I want: If a student has submitted his/her answer (with multiple submissions available) I want the student to correct only the wrong answers and resubmit. When the Reset button appears the student needs to Reset the question to correct answers and this means everything needs to be done over also the questions where the answers were correct.
Any help will be appreciated in this regard, even if I have to post this question elsewhere.
