I was modifying the inputs of a blueprint pure function I created before and found that I could add inputs, but when I deleted the inputs, it appeared as shown in the picture, but in the new function I created it was normal, I don’t understand how it had been fine before and then it suddenly appeared like this, this has been a bug I have found more than once in my development, and it makes me very disappointed!

Iit’s very easy to have one function open in the code window, but another function selected

Could it be that?

I don’t know, I’ve had problems with this function so far, then I created a new function and deleted it after I moved the content over, and I haven’t had the problem again yet.
