Looks okay to me.

Assuming the two lines of code above are 107 and 108 (and that you
indeed copypasted them) I see no reason for this error.

Just replacing "empty appointment filled " in the above code with "xxx"
has this effect? That simply cannot be.

From my own experience I can tell that such incomprehensible behaviour
usually indicates a very simple mistake.

So we will obviously need to see those other lines. Maybe you can trim
them down somewhat. And while doing this you might see the cause of the
problem yourself.

Global search & replace? Or manually just in those two lines?

Shouldn't matter, but one never knows.
