Losing IP boost timer?

I'm not really sure what's going on, I bought a 1 day (24 hour) IP boost yesterday afternoon. I played until last night, only to wake up this morning to "2 hours" remaining on the boost. I am sure I bought in the afternoon, around 4 pm, but now it's pretty much all gone, early.

Just wondering if anyone else is having this issue of losing boost time.

Thanks.
