Usage statistics blank (after installing winterboard?)

[ovisopa]

Hello guys,

yesterday I installed for the first time winterboard, because I wanted to have a more detailed lockscreen. I noticed that since yesterday the usage statistics are not shown anymore, last night, before I go sleeping I fully charged the phone, and for a while the statistics ware there, I seen the usage on 2minutes .. but this morning it's empty again, like you see in the attached pictures.

Any ideea ?
