Weird format with nested json arrays

[Jack8680]

When I have nested json arrays, such as [["test","test2"]], getting the array value at index zero returns:

(
test,
test2
)

Rather than simply ["test","test2"]. Putting this back into an array breaks things because of the line breaks, escaping them as ["(\n test,\n test2\n)"]. Interestingly, the get array value behaviour still works on this format, so perhaps it's intentional, but something is broken in my project so I'm guessing it's caused by this.

Edit: it's not broken, it actually works fine and it was just not working because I was using trim text on the first character to check if it was an array, which obviously doesn't work without square brackets. Get array count works fine though,

Edit2: it actually is breaking something else, but I don't have time to figure out where at the moment.

Edit 2021:
Don't mind me just testing something
