RTC gets printed the wrong way. how to handle strings??

Hi, i just got my Nextion 2,8" touch going and cant be happier. until just now. i've got a Bmp280 pressuer sensor and a DHT22 plugged in just to get some values to display. and added my RTC, and it constantly draw only one number from 0-9. before there have always been a void print2digits that took care of that. but now i dont print my numbers. i just send them as a value to a specific location in my nextion screen. How do i add a zero before 0-9...?? its the same problem with "12:5" single numbers are the problem... plzz..
