I have a filter statement that seems to have stopped working on one of my screens - in the editor when I highlight the filter line, it's saying "We didn't find any data":

I know for a fact that this line should be returning results, so to try to troubleshoot, I took the same code and put it into a new screen. On this screen, when I highlight the same portion of the code, it shows the correct results (you can see that the code is the same):

Anyone have an idea why this would be happening? The code worked properly up until today.
