Good morning @Will the Werewolf,
So, I have watched the clip and saw the issue you are currently experiencing. I believe it might be that your skills are not high enough for that drive or that you don't have the required skills for that actual job (https://truck-simulator.fandom.com/wiki/Skills). I am not sure what it could actually be, as you only showed the clip of the cargo market, but if you are low-level and don't have skill points assigned, then the issue might be there.
From my knowledge about TruckersMP, they post Cargo Market as if you had all your skills unlocked, which could be the reason why it isn't letting you actually select the job. If you are looking to fix this, you can always use unofficial tools like Project ALM or the TS SaveEditor Tool to give yourself the levels and skills you need and then try to take a job. Or you can grind out the levels, which may take more time if it's a legit profile.
I hope this helps <3.
