Welcome to the community, @Zoltan_Babo! :grinning_face_with_big_eyes: Form views are tied to tables. If you have more than one form view on a table, even if the fields are different, all of the data still goes into the same table.
One way to separate the responses is to create unique grid views to isolate the fields for each table. To isolate the actual form responses (records), you’d need to add a filter. Assuming there’s at least one field that’s required in each form, filtering by the appropriate field in each view would get the job done.
If the data collected by each form is different enough, you might consider making a new table for the second form.
