Should I clear form data after a new form is selected?

In my web app we have an area where you can choose the type of "query" you want (left block) and then you see the selected form with the fields in the right

enter image description here

As you can see, 'Risk' field may appear a lot of times since it's available in 5 types of queries.

The question is: Should I keep the data when switching forms? Or should I clear the form every time the user selects a new form?

I explain myself:

  • In the Risk level input, I select something.
  • Then, I go to the 2nd query (Risk + Person type), see image below

  • I need to fill the Risk level input again

At the moment every change of query type, I clear the fields and the user has to select again the wanted value (It may be multiple choice)
Example: with items

Is OK clear the data? Or do you prefer keep the changes between each form?

Additional info: when the user changes the query from the left block, the page is not reloaded, just the fields are updated (shown or hidden). All the fields shown are required to submit the form.

Maybe another approach is to keep the changes between switches and add a reset button in the down-left corner of the right block. Example: reset

What do you think? Any help is welcome

Thanks!
