M4 Chip MacBook Air - 3 External Displays, MacBook mirrors and recognizes them as 1.

I started a new job and was given a MacBook Air with an m4 chip. I have 3 external monitors which I connect to a dell docking display and then usbc into my MacBooks port. My MacBook however is recognizing all three of these external monitors as 1 solo monitor and is mirroring the screen across three of the monitors rather making each it’s own individual desktop. Never had an issue before when using a prior dell work laptop. Assistance is appreciated
