Work authorship in "Assassin's Creed 3. Liberation" release

Greetings.

This is the release:

Problematic/questionable work/recording:
02. “Stealth”

“Surface” data about this release (vgmdb, imdb for example) shows that there is only one and single composer for this release - Winifred Phillips. But if we dig deeper (in PRO units) - it shows several works - ones with only Philips, while others - with Philips and Jesper Kyd (composer from the previous AC chapters), so my question here is which authorship is the correct one.

I suppose if this track contains some elements from the previous chapters (kinda “based of”) it would be logical that it has Kyd as co-composer, but i am not familiar enough with AC albums and cant say if this track resembles something from the previous chapters, so may be other editors could know this.

And here are work numbers from iswcnet.cisac.org:

T-915.667.909-3 STEALTH - JACOBSEN JESPER KYD,PHILLIPS WINIFRED
T-918.245.112-3 STEALTH - PHILLIPS WINIFRED PATRICIA
T-926.858.680-7 STEALTH - JACOBSEN JESPER KYD, PHILLIPS WINIFRED PATRICIA
T-926.858.949-7 STEALTH - PHILLIPS WINIFRED PATRICIA

I dunno if it means something, but all other works from this release begins with 915.
