AXI IIC Master receiver with 10-bit addressing

Hello, I have some problems using the AXI IIC core as a master receiver with 10-bit addressing. I managed to configure it as a master-transmitter with 10-bit addressing but now I need help setting it up as a master receiver with 10-bit addressing. I managed to write the first byte of address (8'b11110xx1) but then I write the second byte of address but after the first ack bit the I2C line goes high like the core is expecting data (see attached screenshot). Please help, I dont know how to do a read with 10-bit addressing. I searched in the documentation and I did not find anything. Thank you !
