Removing parenthesis in a list

I need to create a list without those brackets that appears after using "list from csv table". I know I can use loops to create a new list without the brackets 

but I would like to do it other way because my Initialize blocks are huge in the menu screen.

Reading this: how to remove parentheses when displaying lists? there's someone called Hossein that talked about

an alternative way to do it but I didnt undestand his answer, can someone explain me what it is?

It would really help if you provided a screenshot of your relevant blocks, so we can see what you are trying to do, and where the problem may be.

I have a .txt file like this using Notepad:

a1

a2

a3

.

.

.

an

When I use the block "when file1.GotText" with "set listpicker elements to" "list from csv table text" "get text" I get this:

(a1)

(a2)

(a3)

.

.

.

(an)

I just dont want those parenthesis, because this is a list that has to be deploy in the menu, for information about the own app. My translation has 2 parts: something to put in a list and text for labels, etc.

I know how to eliminate the parenthesis only I select 1 of those items, but in this case I need the list like this:

a1

a2

a3

.

.

.

an

in a list.

➠ to convert a 1 column csv table into a list, instead of the list from csv table block use the split block instead, just split at \n (new line) to get a list
