You've been in a 'Faux-IP2', which is what I call an IP2 long before its time. The traditional transition from IP1 to IP2 to ghost update to PPR still holds but in a modified way due to candidates now requiring biometrics, as well as certain candidates not paying their RPRF upfront, or being a CEC-Inland candidate, for example. You will see a series of 'ghost updates' instead following your MEP; the first will signify your IP1, the second will signify your real IP2, and the third will be your true ghost update, following which you are likely to receive your PPR.
