- IVEZE is the CORRECT identifier for ILS 28C, at frequency 108.95, according to current Navigraph charts, and according to the charts with supply with the scenery.
- The ILS it's included in the scenery AFCAD, as indicated in the attached screenshot from ADE
- The ILS works fine in the simulator, as indicated in the attached screenshot from within P3D, showing the correct identifier, at the correct frequency, and the perfectly lined up localizer/glidepath, which is in perfect sync with the PAPI lights.
So, the scenery is absolutely fine.
If with "inop", you mean it's inop in your 3rd party airplane FMC, that's likely because your navdata is outdated.
