Exclamation Problem with all digits on clock widgets

Hi everybody.
I have problem with my tablet Huawei MediaPad 7 Lite... All clock widgets after a certain time change digits... The problem presents the following screenshot:


My tablet has installed stock Ice Cream Sandwich 4.0.3 with root and TWRP. Default launcher is Apex Launcher Pro in newest version (stock launcher I removed). The problem occurs from the beginning.
