Hello!
I am curious if this is the case in the real aircraft or if it is some sort of graphical glitch - in any way, it is no big problem.
On my last flight the TOD point was exact at the position of a waypoint... first I wondered if there was no TOD calculated, but then I found it behind the Waypoint KOSEB (see screenshot)
You can see green parts of the TOD between the letters of KOSEB.
