Portion of code containing my custom functions is hidden and I cant access it.

So somehow my functions got hidden inside my script and there is the icon that should allow me to view everything that is hidden but for some reason it doesn't. Is this a bug or is there a setting I might have changed by mistake? here is the icon I am talking about, I can't click on it and I can see that there are roughly 300 lines of code that I can't see so I know they are hidden there.

"I can't click on it"

Is the icon not seen in your script at all to click?

The icon is there but clicking on it does nothing.

The feature is called code folding:

Look on the left: between the line numbers and the code itself are some + and - symbols.

Click on the + symbols to show the code again:
