@ellyhiby, let me explain this with an example so that you are able to understand it pictorially.
-
You created a form and deployed them (first deployment). So you should get a form version in your XLSForm as shown in the image below:

If you closely observe, you should be able to see that the form has only 1 question namely
Name. The form version for this form is vM5dHLqGHR4wrNDQarbhdc. -
After deploying, you may have also collected data for the form. Here I have collected 1 record (1 interview or whatever you say) for this purpose.
-
So at this point, say I felt like some questions have been missing in my survey form. Hence I added another question and then redeployed the form again (second deployment). So you should now get a form version in your XLSForm as shown in the image below:

If you closely observe, you should be able to see that the form has 2 questions namely
NameandAge. The form version for this form is vEmE8ddTRUVCS3kjZvuT9Y.* -
Once again, you may have collected data for the form after deploying. Here I have collected another record (1 more interview or whatever you say) for this purpose.
-
If you view your
form historyunder theFORMyou should see that you have 2 form versions for this survey project: -
Similarly, if you view the DATA>TAble and check out the records you should be able to see that you have 2 records that hold the data from 2 different versions viz.
vM5dHLqGHR4wrNDQarbhdcandvEmE8ddTRUVCS3kjZvuT9Y. So this will tell you that you have data from 2 different form versions. If you look more closely, you should see that one version has only theNamevariable while the other version hasNameas well asAgevariable.
This should give you additional information about your form and its version in the data which should be helpful for project or data managers for this project.
