Impossible to install 1 dlc compatible with 2 games

[DarkSoulsFan]

Hardware: PS Vita 1000 PCH-1004
Version of firmware: 3.65 Henkaku
Version of PKGj: 0.57

Steps to reproduce the issue

• [Install europeans versions of Persona 5 Dancing and Persona 3 Dancing]
• [Download DLCs that are normally compatible with both games]
• [Install them]

Obtained result: [Some are installed on P5D game, other on the P3D game depending of their title id]
Expected result: [They should be installed on both games]

[Although EUR "P5D/P3D" DLCs are compatible with both games, they do not have the same title id in PKGj. EUR Persona 5 dancing id is : PCSB01257. EUR Persona 3 Dancing id is : PCSB01256. Half of the DLCs have P5D id and the other half have P3D id, although they are compatible with both games.]

This doesn't sound possible, but if it is, this would be an NPS issue, not a PKGj issue.
