minor bugs in the demo

[vorosj]

The light value and button count value is not visible.
Reason: the ui_lblCountValue and ui_lblCdrValue label points outside the visible area.
I deleted the lv_obj_set_align(xxx, LV_ALIGN_TOP_MID) lines, and added some x offset, and works

Hi,

In the develop I made the image smaller so it does no longer cover the labels...
