Saved files run with old code

Even if a file is saved and the project is built and run, I am seeing Javascript code in QML that the system thinks is old code, even when it has been edited and saved. Attached is a screenshot example. It doesn't just affect runtime, it also effects the editor. The highlighted characters come up in a search for "lot" which was there previously and changed to "log". However, when run, an error occurs that says "lot" is not a valid member function, which is true, however, it is running with "log" now, not "lot" so it still thinks the old code is there, and the editor's Find box also thinks this, even though it is definitely not there.
