Ip count Bug

So my ip before i finish a match is around 4750, when i finished that match with the first win on i got 5070, but the shop recognize my ip count as 4650 something. I know it happens a lot, but it's been 20 hours and nothing has changed. Edit : after a while , i finished another match . It updated the 51 ip i get in that match , but not the one mentioned earlier . So is this a display bug ?
