Importing users - what should final two settings be?

Following up to my post of a few minutes ago, I am clicking "Import" in your extension's control panel, then for "Data Source Format" in the drop-down I'm selecting "Database", and unchecking "Local Database". I then enter the database details, click the "Continue" button at the top left, and am directed to the second screen. I'm then manually selecting values from the various drop-downs - because it requires me to, there's no ability for it to autoload them - but when I get to the final two in my screenshot, I don't know what values to choose. Again, as per my OP, they are:

#__user_usergroup_map: what to select for Column 1 and Column 2 (I'm selecting user_usergroup_map in the initial drop-down)

group_id: what to select for Column, Column 2, and Title (I'm selecting "usergroups" in the initial drop-down).

I'm not trying to create a profile. I'm trying to use your ready-made Import Joomla Users profile. I'm trying to import the data from a remote database and on the first screen am entering in mysqli, localhost, my MySql username, database name, etc. Then I click "Continue" and come to a page that you can see in my screenshot. I then have to manually click each drop-down and select a value. I don't know what values to choose for the final two. Despite my trying to use your ready-made Profile, I am still being required to enter in all of the values manually by clicking each drop-down. I just don't know what to select for the final two (please see my original post). Thanks.

New to this extension. I guess I thought it was going to be much more automated than it is regarding data import from another site. Anyway, for my first attempt I am trying to import the Joomla users. I thought that made the most sense before importing Articles and Categories. I think I understand most of it (I'm not a mysql database expert), but I don't know what the correct configuration should be for:

#__user_usergroup_map: what to select for Column 1 and Column 2 (I'm selecting user_usergroup_map in the initial drop-down)

group_id: what to select for Column, Column 2, and Title (I'm selecting "usergroups" in the initial drop-down).

So I'm kind of in a holding pattern at this point and unable to proceed forward with the whole-site import. Thanks in advance for any assistance you can give.
