Splitting a dvd9 DVDFAB5

Using newest version of DVDFAB5.
When splitting a DVD9 to two DVD5’s I can’t seem to get the “Please Insert Other Disc” screen splash to work properly when selecting a title or chapter that’s been moved.

On disc one if I press an absent chapter it will just go back to the original title menu.

On disc two if I select an absent chapter it will either just go to the next available chapter, OR I will get a split second splash thats not complete, then it goes to the next chapter.

Anybody know whats going on?
