Only one monitor working out of the three connected
 

Hi Guys - I recently bought the Alogic triple display 4k docking station to use with my Intel Imac (2021) (Big Sur 11.4). I have three monitors connected to it. I followed the instruction on the website and have also installed displaylink login extension, however, only one of the monitors is working - having spent the last three hours trying to find a fix, I'm hoping that someone here will have a solution.
