I have seen this too; On the place where the vehicle is stopped.. there is no clear lines on the bus stop, and can be seen on the image.

Taxi and private hire drivers can stop to pick up or drop off customers in many areas where there are waiting or stopping restrictions. Drivers should be aware that:
Taxis and private hire vehicles can only stop as long as is necessary for the customer to get in or out of the vehicle. This includes more time to assist wheelchair users and to make sure that the wheelchair is in the right position and safely secured
Picking up or dropping off is allowed on single and double yellow and red lines, in places where loading is not allowed (shown by markings on the kerb), in parking bays and in bus lanesBus lanes & bus stops
Taxis and private hire vehicles can pick up or set down customers in a bus lane even if they are not normally allowed to drive in it. The only exceptions are stretches of red route where stopping is not permitted because of the disruption this would cause to already busy roads. Taxi and private hire drivers should be aware that:
Drivers should enter and leave the bus lane in the most direct and safe way
Customers should never be set down in the middle of the road, even if the vehicle is stopped due to traffic - the driver must always get close to the kerb
Private hire vehicles cannot stop at 'bus stop clearways' marked with a wide yellow line by the kerb. On red routes both taxis and private hire vehicles cannot stop at bus stops marked with a wide red line by the kerb. At other red route bus stops, taxi and private hire drivers should avoid stopping to avoid disruption to the bus network
Remember, only licensed taxi drivers can drive in bus lanes - private hire vehicles are not allowed. Licensed taxi drivers should check the signs at the start of the bus lanes, however, because there are a still a number of bus lanes they cannot use
I am just a bit wary that the appeal time is pushing close too :/
