If you have code like this:

list1 = [];
list2 = list1;

this error is normal. You need give more information about this issue.

You certainly have a line like this:

_tempccToListSelected = _ccToListSelected;

or the opposite.

This line don't copy list into another one but make a pointer to the other list (like in numerous language).

If you want to copy (duplicate) the liste use spread operator:

_tempccToListSelected = [..._ccToListSelected];
