UI Kit Picker Font Size


I`m trying to use the Picker on an iPad Pro 9.7" and it seems that no matter what i do the Picker font size is like double the size of all the other controls on the screen and it seems that i cannot select or modify the font of it .

How it can be done ? and it can be done first of all ? Even the font looks different, it cannot use the system font and size to blend seamlessly with the other controls ?
Thank you .
