Hello, whenever I try to change a field e.g. speed in the data page display, a white box with rounded edges comes up - but there is nothing selectable (no text inside). So it is impossible to modify any data to be displayed

Also when I press inside this box nothing happens. I can exit this box by clicking somewhere outside this box.

Another suggestion: the fields in cartography display (zoom +, - data fields at lower screen, selection fields upper right are VERY VERY small. It would be very good to be able to select their size (small-medium-big).
