I2c Bus. Cant get more than 1 slave on network

Im trying to get my mro ms4525 sensor (with level changing ic) to work in parallel with the gps/mag on the 6 pin gps i2c port of a pixracer.
When i connect just gps or both airspeed and gps, i get gps working and constant zero from the airspeed.
If i just connect the airspeed sensor to the port, it works and i get airspeed data correctly.

Any idea, conflicting network addresses maybe?
Happy Easter to all

Gave up on this, Pixracer and gps were clone items, although I could get both the gps and airspeed to work individually, i’m thinking that there are issues of unsupported hardware in the pixracer clone, I don’t know.
