I haven't used this bug reporting thing before so sorry if I mess something up.

Anyway i'm not sure exactly what is causing the issue but the issue appears when you have a for loop looping through an array and you make a variable and set it to that array and append something to it. If you do the same thing with numbers it works as expected but if you do it with an array it for some reason doesn't get reset every iteration. Run this and you'll see what i'm talking about.

Arr = [1,2,3,4,5]
for num in Arr:
    Arr2 = Arr
    Arr2.append(1) #the 1 can be anything
    print(Arr2)

Also i'm interested to know why this happens, Thank You

I found out it just happens when you set an array to an array they behave as the same thing, which if its not a bug it sure is counter-intuitive. 

if you do
x = 1
then 
y = x
then add one to y you have y = 2 and x = 1
if you do it for an array
arr1 = [1]
then set something equal to that
arr2 = arr1
you essentially have 1 var that act on each other which is odd
so arr2.append(2) or arr1.append(2) make both arr1 and arr2 equal to the same thing

This isn't a bug: it's the way that Python's assignment model works.

This is explained in various places (including the official Python documentation), but you may find this excellent presentation by Ned Batchelder useful: https://nedbatchelder.com/text/names1.html

I will check that out, Thank you
