I have a problem because my gpi02 and gpi03 pins are not working with ic2 . I have an overlay in the config.txt file to different pins on BUS3. But the witty pi 5 wont see this bus. How can i get around this issue.

Why are your GPIO2 and GPIO3 pins not working with I2C? These pins are by default used as I2C.

If you need Witty Pi 5 to use different pins as I2C bus, you need to do the hardware wiring yourself, and you may also need to modify the software.
