Data icon missing

Hello I bought this amazing app, and everything works except the data icon (it simply doesn't show up). I sent you an email before (to the email that is on play store), but then I found the post on xda saying to post the problems here, so here you go.

btw, i'm using a UMI Zero (chinese phone), but it has the Huawei G750-T20 rom (EMUI 3.0).

Hope you can solve this problem :) Thanks
