Hello, could you please embed your flow as an image in the body of your question, above?
As you may have already noted, your attachment is being held back for scanning, plus, many people just cannot access the attachments full stop. :-(
Embedding avoids the doubt. 👍
In the meantime, I am just going to throw out a guess that you may wish to use separate Selects for separate purposes, here.
For example, if you want a 'simple' string array of one of the values, you can make that using the 'text' view of the 'Where' / 'Map' field in the Select action.
To take that example a stage further, let us pretend there is an email key named 'email' with values in all the objects, and you want a list of all the emails.
To get that you would take the array, tap the 'text' button on the map, and enter an expression in the expression builder that simple states:
item()?['email']
That would produce a list of emails (with repeats, that you can union() out in a later action) you can then use for whatever purpose is needed.
Equally, there is a chance that there are a few xpath() solutions to achieve really good results in one go!
