Hi Joey,
It is by design, for each submission, all submitted value will be saved in one field: "Form Submissions"(msdyncrm_submittedvalues).
An alternative is that you could build a Marketing Field Submission based report, and link query to Marketing Form Submission entity.
Then you result will be below:
Field Name Value Contact Timestamp
Last Name Joey Joey K 22/06/2020
First Name K Joey K 22/06/2020
Company Name Info Trek Joey K 22/06/2020
...
How did you hear about us? 6 Joey K 22/06/2020

Clofly
