No sensors detected on raspberry pi zero W 2 - Check whether I2C enabled and Grove Base Hat RPi or Grove Base Hat RPi Zero inserted

Hello team,
I have setup my raspberry pi zero W 2 with raspbian legacy and followed the hat setup instructions but none of my 4 senors (4 digits display on D5, button on PWM, 6 axis accelerometer on I2C, GPS air 530 on UART) are detected althought i tested the ports and the gps led is blinking.

I checked i have an ST chip on my hat and modified the three files with 0x04 but it didn’t change anything.
How can i finally get these sensors to work ?
