Fields are required to be filled out even though not set as required (1 Viewer)

I have made a form based on related tables. it requires me to fill out every field, which I don't want. I didn't make them required. Why does it do that?

You need to give us a lot more information. Can you give us the table structure and fields from the 'Related tables' and how you are putting them on the form.

Did you set an index on the fields - if so what type? Etc etc.

I have included the file with tables and the form. I didn't set any indexes. it seems like because all those values come from the same table, they are all related and therefore required.
There are 8 related tables that feed the main table. The form cannot be saved until all the fields are filled.
Maybe the tables should be set differently?

Only for info:
There are a lot of indexes, open the table "Participant Information" in design view, click at the "Indexes" icon at the Ribbon/menu line.
But it wouldn't help you only to delete them, because you've related/linked all the tables you've to the "Participant Information" in different fields and that require you've to fill these fields.
If you don't want to fill these fields then delete the different relationships.
