Reading 2-channel current monitor via Anyi2c

Forgive my very basic question but how do I properly query the I2CCMAC220A through Anyi2c? I choose the board on the left hand side (i2c Current Monitor I can only assume as it has the current device address of 0x2A) and then run the first command Reading Current but only one byte is returned rather than the four expected from the manual (MSB, MSB2, LSB and checksum). What am I missing? Attached is a screenshot.

do you get any error is click GUI?
