Recent Soundtrack links not showing on filmographies

Recent added Soundtrack links are not showing on the person's filmography.  They did briefly, but then vanished again.  I know Soundtracks have always had this weird, different way of being added to every other credit, but it has still always worked in the past, using both the original and the current linking methods.  The previous downside I saw when the linking method was changed, was that if you copied the number down wrong, it would link to the wrong person, and you wouldn't even know as it doesn't show the name when you input the number link, but still it always linked to somebody!

260501-185019-294000

260501-185612-534000

I also added some Soundtrack credits on the same day, and they do seem to still be showing

eg 260430-203217-633000

However, this obvious mis-formatted credit of name reversal also failed:

260430-215547-450000

So it could either be a problem with that particular day, or more likely one related to correcting Soundtrack links.
