That is the usual suggestion that often works. Did you try another time for Friday (an hour earlier, or the same as the rest of the weekdays, for example) to see if that made any difference?
There don't appear to be many (or any?) other reports of this on the forums, so I have doubts it is a bug that was introduced, otherwise I would think others would also be seeing this.
I don't see anything obviously wrong with the way this is written. Maybe @ogiewon or someone else can see something wrong with the rule above where I do not, I don't use Mode Manager so I might be missing something here.
