Select Node Bug with Null References?

The float one pops null references, while the text one does not. I guess I just dont know why the select is trying to read a value that it doesnt need to look at, and it’s even weirder that it only seems to be a problem with floats.

These are to update bindings in a UMG widget. One updates the tool tip and the other updates the progress bar.

Any ideas?

ah to clarify, i actually just looked into this some more and text also has the same bug, but the tool tip only renders when its activated (so it only popped errors once i activated it by hovering mouse over the progress bar).
