Is length function acting buggy for anyone else?

There are 2 functions named length according to documentation: length for Arrays which counts items in array, and length for Strings which counts characters. 

In this video I am setting a variable where, if the length of a string is longer than x it will return one value and if not longer, then it will assign a different value to the variable. 

You'll notice that right before I save it and mouse over the length function it shows the guidance for String length. But after I save the module, mousing over shows the guidance for Array length.

I'm not sure if Fusion is actually swapping out the String function behind the scenes with the Array function of the same name or it is just mis-printing what appears in the mouseover text. 

However, after I run the module, regardless of the length of the value that I input, it is always outputting the variable as though the If condition were true. Can anyone...

a. duplicate what I see with the mouseover text?  and / or

b. spot where I might have built this module wrong (provided the length function is NOT buggy)? 

For a bigger view of the video if you can't see it well enough inline, you can watch it here: https://youtu.be/DiHyF2NIoDo

Thank you.
