ᐅ Lintel over Garage – Missing Concrete: Is This a Problem or Nothing to Worry About?

Good morning everyone,
I have been following this forum for a while and now have a small question about our current house construction. I already asked this question in another forum but am still unsure and am posting it here again. I have also learned that in this case it is not a lintel in the classic sense. However, due to a lack of alternatives, I am still using the term.
So, above our garage, a lintel was formed and cast over a length of 7m (23 feet) and a height of 1m (3.3 feet). Now, it seems the construction workers miscalculated the amount of concrete. This means that on a length of about 1m (3.3 feet) and a depth of about 20cm (8 inches), concrete is still missing. This will probably be poured today. Now my question: since the already poured concrete has partially dried by today, is it possible that the concrete poured today will not properly bond with the existing concrete? I want to know whether this could cause any issues with load-bearing capacity, deflection, or strength. Or if this is not a problem at all. Before I raise an issue with the construction company, I want to make sure if there is any valid reason to complain. Pictures attached.
Thank you and best regards

Above the garage door, the garage, which is slightly set forward, has its own lintel.
The part I am concerned about is the beam that is supposed to distribute the loads, as mentioned. A support column in the middle of the driveway was indeed not desired.
I had some difficulty with the terminology. I have attached pictures from the structural calculations. For this beam, the amount of concrete was miscalculated, so the section shown in the pictures was filled in one day later. Now, if I understand you correctly, this actually represents a bigger issue.
Any advice on how I should proceed now?
Thank you and best regards

Hello
I would report the pictures to the structural engineer.
He must have had a reason when he designed the concrete cover.
Also, later filling with concrete could allow moisture to penetrate at the contact point. Frost is not to be underestimated. Moisture on the reinforcing steel is especially problematic.
