I2C Countdown Clock issue

Hello,

I tried to make a simple countdown clock following the steps on this site .
I did everything according to this page, ordered the parts and connected them according to the circuit diagram. However, when I load up the test code (which is a countdown for Halley's comet) it returns this error message:

C:\Users\Till\AppData\Local\Arduino15\packages\adafruit\hardware\avr\1.4.9\libraries\Wire/Wire.h:65:13: note: candidate 1: uint8_t TwoWire::requestFrom(int, int)

uint8_t requestFrom(int, int);

^

C:\Users\Till\AppData\Local\Arduino15\packages\adafruit\hardware\avr\1.4.9\libraries\Wire/Wire.h:63:13: note: candidate 2: uint8_t TwoWire::requestFrom(uint8_t, uint8_t)

uint8_t requestFrom(uint8_t, uint8_t);

^

The displays are working but they are showing something different, 2354 0622 instead of 2354 1120. Maybe the second display is the issue? I don't know what to do, I don't even understand the error code. Does it even have something to do with this fault?

However, when I load up the test code (which I couldn't be bothered posting) it returns this error message

There's a clue above.
