JQuery Learning Section Bugs

Good day good people. The JQuery section has bugs. Am I the only one experiencing this problem. The instructions say one thing, and the evaluating script marks something else. e.g. you will be told to delete everything in the $(document).ready() function and type the answer. When you view the solution after your answer worked well and gave the desired output, you find that the solution provided did not delete the previous code. Here is an example below of one that worked but is marked wrong during test

This looks like the same behaviour as:
